Unable to access certain sites

Since early yesterday morning I have been unable to access several internet sites, including, for example, LastPass.com. No hardware, software or settings were changed. I can access these sites on my iPhone with Verizon wireless and today I was able to access all of them from work (with a non-Verizon Fios ISP). Again, it is multiple sites that I simply cannot access which is causing problems. For example, in addition to not being able to use LastPass, my Evernote account will not sync.
I have tried the following:
(1) Deleting temporary internet files, cookies, etc. and flushing the dns;
(2) Rebooting my router mutliple times;
(3) Turning off my firewall (even though nothing has been changed...); and
(4) Spending an hour with Fios technical support which, after completely resetting my router, resulted in nothing except the rep offering to sell me premium suppport service...
I have heard of Verizon sometimes fighting with certain other providers or pipeline providers (?), where access can be temporarily limited. Since this problem is affecting my computer (wired to the router), as well as all the other (wireless) devices in my house, I really need to find a solution as soon as possible.
Any suggestions? Does anyone understand how provider/pipeline disputes my disrupt access to just certain sites? Any way to verify that?

Glad to try to help... There are a few suggestions here http://www.makeuseof.com/answers/dns-error-sites-open-fine-pcs/ . I would try changing your DNS server on the router ... This procedure http://www.verizon.com/support/residential/internet/fiosinternet/troubleshooting/network/questionson... will get you to the correct screen BUT use 8.8.8.8 for Primary DNS server, and 8.8.4.4 as secondary

After updating to 10.4.11 unable to access certain site.

Since I updated to 10.4.11 I am unable to access the site: www.wdwinfo.com. My wife would listen to a podcast hosted by the site. iTunes just keeps spinning away that it's looking. I tried all four browsers on my machine to see if I could reach the site (Safari, Camino, Firefox and Flock). I cleaned all caches and histories. I am able to get to the site on my ipod touch on my neighbours open wifi. I can even ping the site on my machine and get a response but as far as my browsers and iTunes are concerned they just sit there waiting to connect. I called my ISP and they can get the site no problem. I tried another computer in the building that is with the same provider and they have no problem. All other websites and podcasts work fine.
I'm running 10.4.11 on an 1.83GHz Intel iMac.
Any help would be appreciated.
Thanks
Mark

The 216.167.116.52 address worked for about an hour while I downloaded the podcasts and then stopped working. I entered the DNS Server number you mentioned in the network settings but I'm still back to no access.
The setup I am working with is ExpressVu TV/Internet for condos. The phone company (Bell) setup a main frame in the building and provide my TV and internet over the same cable. The motorola box set top box had a modem installed into it when they were setting it up. Ethernet from it to my Mac. In my network setting it shows that there is a router in the path. Would the router trump me putting in the DNS numbers? I'm guessing the router is sitting at the mainframe in the building.

Unable to access certain sites- network prefences help?

I'm having issues connecting to certain websites with 'unusual' top level domains like .me or .tv sites. For example, when I try to visit the site www.formspring.me I get the message "Firefox can't establish a connection to the server at www.formspring.me." (I get the same error on Safari) Now, I can access Formspring via a proxy site, which makes this seem like Formspring is being blocked via a firewall, except I have no firewall set. I spoke with my internet provider (Verizon) and they are useless.
I'm operating on Mac OSX 10.5.8. I have no firewall set on my router, and haven't touched any Network settings that I know of. Any suggestions? Help?

Ok, I tried that and I still get the error "Unable to Connect."
I've tried using my laptop on other internet connections (at my friend's house, at work, at Starbucks) and I still get the "Unable to Connect" when i attempt to open sites that end in .me or .tv
I called Apple and they didn't do anything- they kept saying it was my router's problem, but since I've tried other internet connections I think it's my laptop's issue.

HT1338 unable to access certain websites

Unable to access certain websites using safari browser. any ideas!!!!

One of the first things you want to try is if you can get to these same sites on TMG itself. Create an Access rule that allows HTTP and HTTPS from Localhost (TMGs network adapter) to Anywhere (it's under Computer Sets). Apply it and then make sure that IE
is not set to use anything for a proxy. Clear all the boxes. Can you browse these sites? If not then your proxy clients will not be able to. Open a command prompt and use nslookup to see if TMG is resolving the sites. Remember that proxy clients rely on TMG
to do the name resolution for them. If it is not working then you will have a problem.

Can't access certain sites only on firefox even after reinstalling

Hi,
Today I couldn't access certain sites like my university site and google (had to use yahoo to search). I tried restarting FF in safe mode, reseted FF to factory settings, deleted FF and erased all its data and reinstalled FF23.......
But it still doesn't solve the problem. I have no problems accessing these same sites with another browser. When I access these sites with FF, with by clicking search on my search bar or clicking a bookmark or hyperlink, FF just gives me no response, as if I didn't click anything. If I click to open the link in a new tab, it just displays a blank tab as if I've just pressed Ctrl + T
Can anyone help me with this please? Thanks.

Hello ashash, check if your firewall or your security software blocks firefox access for the specific sites.
thank you

I want to change the location of my MacBook Pro. I live in Mexico but I want to have it located in the US so I can access certain sites.

I have no idea if it's legal or not, but you could use a proxy software to "spoof" your location.

Unable to access certain web servers after creating time capsule network

Since creating a home network with Time Capsule, there are certain web sites or servers that I am unable to connect to. The browser attempts to connect, but always gets timed out.
One site, for example is a link from my fantasy football homepage: football30.myfantasyleague.com
I have no trouble with any other site, and am able to get to the address above if I connect my Mac directly with the Cable Modem, thus bypassing the time capsule network. Also, if I use my old wireless router, I am able to access the address without problem. I am also able to ping the address on my time capsule network,
I've tried accessing this site on multiple computers (both mac and pc) through my home network and using multiple browsers (Firefox, Safari, and IE). So the problem must lie with some time capsule setting (some kind of default firewall). However, I cannot find any setting on Time Capsule or Airport utilities where I could make any adjustments or view any prohibited site access.
Does anybody know why this particular site is constantly blocked when I use the Time Capsule as my router?

hamish,
Welcome to the Apple Discussion!
I'm wondering if either or both Airport Utility & Network Prefs have proper DNS server settings. Try this
Launch Airport Utility.
Select TC on left.
Click "Manual Setup".
Select "Internet" from the toolbar above.
What's listed for "DNS Server(s):"?
Try putting in these servers from OpenDNS [http://www.opendns.com>
208.67.222.222
208.67.220.220
Click "Update".
Your TC will restart with the new settings.
Next, launch System Prefs --> Network Prefs.
Select the service you usually connect with on the left (Airport or Ethernet).
Then click, "Advance..."
Click the "DNS" tab.
What's listed for "DNS Server(s):"?
Usually "10.0.1.1" will be listed first in gray. This refers back to the settings in the Airport Utility.
Nevertheless, it doesn't hurt to add the DNS servers noted above here as well.
Click "OK" then click "Apply".
Now see if you can access those websites again.
Cheers!

Unable to Access Web Site (with same name) outside of Local Network

Hi everyone,
I have my web site (and some other services) hosted outside of my network by my hosting provider, but handle all other items using OS X Server on my network (i.e. Wiki and so forth).
The problem is now that I am unable to access my website at www.mydomain.com from within the network. I have external DNS set up for www.mydomain.com to point to my website, while mydomain.com points to my OS X Server (static IP address). Internally in OS X Server's DNS settings this used to work when I had www.mydomain.com resolving to the IP address of my web host, in addition to the default domain settings that OS X had set up. For some reason this is no longer working, and I am unable to figure out why.
Using latest version of OS X Server 3.0.2.
Any help is greatly appreciated. Thanks!
Update: this ended up being a redirect issue on the web host. I added another subdomain that was hosted externally, and it worked fine. For some reason my web host is redirecting www.mydomain.com to domain.com.

I am in Texas and cannot get to that site either. Do you know for sure the site is up and working? It could just be down (for days, a site I support was down for almost 4 full days a few weeks ago due to a virus problem).
This may (again, may) be your problem: I see you have a173.48.x.x (you really should x-out the last two octets of your IP address for privacy reasons), I am on a 173.74.x.x address; I know some people have had problems with getting to some sites now that they have a 173.x.x.x address. I think Verizon obtained addresses in that range and some of the addresses apparently previously belonged to spammers or some malicious folks.Some sites (web sites, intermeidate routers, etc.) blocked those addresses, and may not have updated their filters to remove the block on those addresses because they don't know that Verizon now owns them. If this is the problem, eventually those filters will get updated and you will be able to access the site, but this could be a fairly long time.
If you know how to contact that site I suggest you email them about the problem. You can also try turning off your router overnight and when you turn it back on the next day you may find that you have a different address (one that doesn't start with 173) that will allow you to get to the site.
I don't think there is much Verizon can do to help, it is not their site that is blocking your address (at least I don't think it is).
Hope this helps.

Unable to access certain websites

for the past week or so I've been unable to access a number of websites. they're timing out halfway through the connection. other sites hosted by the same companies work fine. looking through the archives i found a similar issue from a year ago in MD. I'm in MA. a group ticket was opened for that MD issue and the problem ultimately was resolved, although i'm not sure what the problem or the solution were.

Unable to access secured site for some

Greetings.
I have setup a secured website on a 10.4 server. The site is the default page in the WebServer\Documents folder.
I can access it fine from work and have had others access it without issue from computers at their homes using typical ISPs. However, when I try to have other access it from other locations using the same login and password, such as a business with its own networks, they are unable to connect. They get back an error message saying the password is in correct.
Everyone can access the site when I have the security settings turned off.
I have set up a realm to handle accessing the site. I have the following also enabled:
WebDAV
IP addess is set
domain is set
I am using Port 80
Realm authorization is set to "Basic"
Performance Cache is on
I DO NOT have the following on or active:
SSL
SSI
I am sure I am missing something else.
Any input would be greatly appreciated.
Thanks in advance for your help.

Open the terminal window in the iMac and enter the following command:
traceroute \[domain name here\]
That will trace the route from your computer to their site and you will be able to see where it stops. There are a number of things that might cause this kind of problem:
1. The website is down
2. There's a network problem between your ISP and them
3. They are blocking your IP address or your ISP for some reason
4. Content filtering or the firewall in your router is blocking the website

Leopard on a Digital Audio G4 - can't access certain sites

Specs:
Digital Audio PowerMac G4
1.5GB RAM
1.7GHz G4 Sonnet Encore/ST; previously 733MHz stock G4
Leopard (10.5.8)
Network is controlled by a router running DD-WRT v24-SP2.
I am having a horrendous time trying to get this specific Mac to access certain websites - namely, anything to do with Google or Yahoo. I can't get to YouTube, I can't get to ANY Google site (including non-US domains), I can't get to Yahoo (or any of its services, like Flickr, del.icio.us, Zimbra, etc...)...obviously, this is getting a tad frustrating. I've been relegated to searching with Microsoft Bing for the time being...oh, the irony...
At any rate, I've tried flushing the DNS cache (dnscacheutil -flushcache), flushing the routing tables (route -n flush, route -v flush), assigning a new IP on my LAN, using other DNS servers (OpenDNS and Verizon), putting the machine in the router's DMZ, and sacrificing a kitten to the flying spaghetti monster.
None of these things have worked. I cannot figure out for the life of me what the problem is. It's not a DNS issue - I can ping google.com and it resolves it to an IP...of course, pinging fails since I can't actually connect to it. I've also tried connecting to other known good IPs for google.com.
I don't see this problem on any of my other Macs running OS 9, Tiger, and Leopard. I don't see it on any of my machines running Windows (XP Pro, Vista Ultimate, Server 2003). I don't see it on my iPhone or my boyfriend's iPhone. I only see it on this one machine, and it used to not be a problem. I'm going nuts trying to figure out what happened.
Any help is greatly appreciated.

Nope. In fact, here's a comprehensive list of what I've tried:
using other DNS servers
flushing the DNS cache
flushing the routing tables
removing the ethernet interface and re-adding it
creating a new location in the networking preferences pane
installing an Airport card and using that instead of ethernet to connect to the network
setting up a static DHCP IP on my router (using MAC registration), releasing the old IP, and picking up a new one
putting the machine in the router's DMZ
trying tracert or ping to get to external domains and IPs
clearing out /tmp in case some temporary file(s) were causing a problem
setting up a new user account and logging in with it
There is something low-level in the system that's causing this problem. Trouble is, I have no clue what it could be. I'm right now downloading the combo updater in the total off chance that it will replace whatever corrupt file is breaking my Internet connection.

Unable to access ftp sites

with the following page displayed after acknowledging the popup:
The connection was reset
The connection to the server was reset while the page was loading.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Cuting-and-pasting the same URL into IE 11.0.9600 results in the page displaying with no problems. Therefore, there is none of the 3 suggestions is the problem.

The county ftp site doesn't act strangely for me.
I'm not sure whether these general suggestions are applicable to ftp sites, but just in case:
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
"3-bar" menu button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* (menu bar) Tools > Page Info > Security > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try reloading the page. Does that help?

Hub disconnects when I access certain sites

My infinity home hub has started outing (green flashing light) when I access certain websites with webstreaming content. What does that mean? What can I do about it?

Someone else reported that on a Hong Kong traffic cam site. The only soulution I could see was to replace the Homehub with something else.

Long delay accessing certain sites using a WRV54G

I am using a WRV54G with Verizon DSL. The firmware version is 2.39.2 and I am using the default settings. The problem I am having is that certain sites take up to 30 seconds to show up. Most of the time, it is when a site launches a secondary window. I am experiencing this on both an XP Pro SP2 laptop using wireless as well as a wired computer running Vista Business SP1. The same sites consistently exhibit this problem on both computers. Both computers are running FireFox 2.0.0.12. These same sites come up immediately at a different location on a Vista machine running FireFox. This is why I suspect the router. Has anyone else experienced this, or does anyone know of a solution? Thanks! --Bruce

Your Westell "modem" is actually a "modem-router" that uses the same 192.168.1.x address space as the Linksys WRV54G. This is likely the cause for your problem.
The easiest way to test this hypothesis is to disconnect the WRV54G from everything else, then, using a computer wired to the WRV54G, change the "Local IP address" to 192.168.2.1 , then save your settings. Power down the WRV54G, reconnect your system, and test. If this corrects the problem, then my hypothesis is correct. This is also the same as solution 3 below.
There are 3 solutions:
1) The ideal setup is to convert the Westell to a plain modem, by setting it into "bridge" mode. This should work with almost any Internet connection type (PPPoE, DHCP-automatic, Static, etc.)   except for PPPoA. If your ISP uses PPPoA (I don't think Verizon uses PPPoA), you will need to use method 2 or 3 (below), because the WRV54G cannot do a PPPoA login. With the Westell set to bridge mode, the WRV54G will handle your Internet connection (including PPPoE login if needed), and all router and wireless functions.
2) Use the Westell as your primary router, and convert the WRV54G to a WAP (wireless access point). In this setup, the Westell controls all your router functions (DHCP server, port forwarding, etc.), while the WRV54G would only control your wireless settings. In this setup, the Westell (not the WRV54G) is providing the protection from Internet hackers.  The WRV54G is providing protection from wireless intruders (assuming you are using encryption).
3) Use the Westell as your primary router, and use the WRV54G as a secondary router. In this setup, both routers are providing protection from Internet hackers. The WRV54G is also providing protection from wireless intruders (assuming you are using encryption). The downside of this setup is that some network devices (such as Xbox and others) do not work properly, or at least do work easily, when connected through a double router setup. Ordinary web surfing and file downloading usually works fine. But if you need fancier stuff, like port forwarding, you have to setup both routers to allow the port forwarding. Some users have had email setup problems with double router systems, but eventually these problems can usually be solved.
So, which method do you want to use? 1, 2, 3 ?
I think 1 would be the best, assuming you do not have PPPoA.   Obviously, option 1 also assumes you can get the Westell into bridge mode. Most Westell users seem to be able to do this.
Option 3 takes advantage of the WRT54GL's wired and wireless router protections, but may make it difficult to use some types of Internet devices.
