"Safari can't connect to the proxy server"

Hello again...
My 10.6 Server is up and running! thanks for all the help...however...
When I try to access the internet via Safari from the actual server, I get the "Safari can't connect to the proxy server" message" but all the client machines can successfully access the internet....
I'll start to read up on proxies but if someone can offer a suggestion in the meantime, that would be terrific. I know it's something simple I am missing...
thanks!

No snarkiness taken Mr. Hoffman...As a full-time high school teacher, I've been setting up our small school server on my own time for the past three months...with the help of the server docs, manuals, and the great help found within this forum, we are finally to a point where we can begin using the server.
What I'm just not understanding is WHAT proxy do I use? I see all kinds of proxy servers out there but is there a specific one I should be using?
Again, forgive me for my ignorance on this matter...I just don't understand why after a year of not using a proxy server, all of a sudden we need to have one? And this issue came about when Safari was unable to "connect to the proxy server"...

When IT folks (or parents) are looking to monitor or control or track network access.
up to this point I don't believe we were using a proxy server?
2) A proxy "regulates" what traffic is passed between machines?
A proxy can enforce access, or can cache access, yes.
So no proxy in effect means traffic goes unchecked between computers...?
Correct.
do we HAVE to use a proxy server with the server?
3) Where does a proxy take effect? At the Router/Gateway? The Server? or >individual machines?
A functional proxy requires a proxy server, and settings at the firewall, and >on the client box.
The proxy setting can be established via WGM, or locally via the system >preferences, or (and the following are less common) via malware or such, or due >to a bug. These settings are usually altered with WGM and system preferences, >in the vast majority of cases.
Enabling a proxy server on the snow leopard server should help us out...but again, which address do I use? (in the server doc you referenced, it had "proxyserver.apple.com:8080")but I think that was just the format to use...
Without intending any snark, read the manuals? Servers are big and complex >and expect an understanding of much more than the client boxes do; that's the >inherent difference between "server computing" and "client computing", after >all.
I'm definitely appreciating how much involvement and understanding it takes to get one of these set up...and over the past three months, we've come a long way...
again, thanks for the guidance and help!

  • Safari can't connect to the web proxy server (HTTP)

    Hello,
    I have following problem. I need to connect to the internet using a proxy server. I went to System Preferences/Network/Wi-Fi/Advanced.../Proxies. Then, I selected Web Proxy (HTTP) and enetered server's IP address and port. It looks like I did everything correctly, but Safary can't open any page because "Safari can't connect to the web proxy server (HTTP)". Does anyone know how to solve this problem?

    There are three possibilities:
    1. You entered the wrong address and port number for the proxy.
    2. You entered the wrong user name and password, if applicable.
    3. The proxy doesn't work or is incompatible.

  • Safari Not Loading Web Pages (Safari can't connect to the server)

    I'm seeing increasing problems with Safari being unable to connect to websites. When the problem starts to manifest itself you see the error:
    Safari can't connect to the server.
    Safari can't open the page.
    Then you see the URL information. It is always seems to be sites that are trying to load HTTPS pages.
    Clearing the cache and resetting Safari will make it go away temporarily, but it always comes back.
    Note that when this happens you might happen to see something like this in the address bar:
    file:///Applications/Safari.app/Contents/Resources/

    I'm having the same problem, I can open safari but when I try to go to a website it just says "server stopped responding." I just updated to the new version and that's when it started happening, it was working find before the update. Any suggestions???

  • Problem with Safari **Safari can't connect to the server**

    My internet is working fine, but I keep having to refresh the page because I'm always getting "safari can't connect to the server".  Same thing happens with different browsers.  I've read a couple things online and unistalled everything that I think is causing the problem but it's still happening frequently.  Any help would be greatly appreciated!

    Most school networks are closed networks. You can access their Intranet, with all the files and peripherals and everything, but you need to have a specific password or IP address to access any outside connection. I have an ibook G4 that's 3 years old. I used it in high-school to access AOL wirelessly. That was before closed and protected networks were prefered. It shouldn't matter if the school intranet is widows based or not. You need to access your own internet service sometimes in order to get any reaction. If you simply use safari, you might only be connecting to the schools intranet, which only links together the schools computers and keeps the system isolated. Also, you need to check your firewall settings, in fact, just turn off the firewall. The schools sytem is firewalled up the bum and you shouldn't get attacks anyway because you're running the mac os.
    You might also try an alternative approach. Go into a computer lab, access one of the systems, then go to control panels and look up every connection you can find. Take down all of the info and then see which matches up with similar info on your mac. Then go to another pc and look up the same info again. Is it different? How? Then take that listing to the system administrator and show them. They may not know that a mac has a simpler interface than the pc, so you may have to do some prodding to get them to take a look. If they still tell you it wont work, you could try boot-camp or a virtualizer (to let you run windows alongside the mac os). If you use a virtualizer, you can get your own copy of windows and then share it's connection to the main system to the mac.

  • "Safari can't connect to the server".

    Today when attempting to launch Safari, 'Little Snitch' tells me that:
    "Safari wants to connect to www.i.google.com on port 80 / IP address 72.14.213.105 / Reverse DNS Name pv-in-f105.1e100.net "
    When I 'Deny' this I get the message that "Safari can't connect to the server".
    I do not understand how or why i.google is preventing my access to the web.
    It's never happened before and Google is not my home page.
    Do you have any ideas?

  • Safari can't connect to the server - still causing problems

    Hi
    I have read through several topics relating to this problem - but have yet to be able to resolve the issue. So apologies in advance if it has already been answered in one of the many threads.
    I have 2 computers both working off the same broadband hub connection.
    Both have the same version of the OS and the same version of Safari: OS 10.4.11 and Safari 4.0.4
    I have checked that the network settings are the same and all parental control settings are the same.
    The laptop will access sites that the desktop will not.
    Can anyone shed some light as to why numerous sites I try to access on the iMac result in a Safari message "Safari can’t connect to the server".
    Same applies when I attempt the same sites with Firefox.
    I have emptied caches, resolved all font issues, addressed terminal and plists etc. etc. - all to no avail.
    Help!!!

    Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:
    If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
    208.67.222.222
    208.67.220.220
    (You can also enter them if you click on Advanced and then DNS)
    Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
    http://support.apple.com/kb/TS2296
    If your computer is part of a network: please refer to this page: http://www.opendns.com/start/bestpractices/#yournetwork and follow the advice given.
    You could also try these codes as well: 4.2.2.1 & 4.2.2.2
    If you use a Router, make sure it has the latest firmware installed.

  • Safari can't connect to the server, but firefox can

    i have a few websites (mainly google sites) that don't show with safari but they do with firefox
    i'm getting a "Safari can't connect to the server" error
    to take DNS out of the picture i am looking up the ip address for the server and use the ip instead of the domain name so
    http://74.125.19.103/images?client=safari&rls=en-us&q=test&ie=UTF-8&oe=UTF-8&um= 1&sa=N&tab=wi
    works in firefox but not in safari
    any ideas are more than welcome.
    thanks,
    tom

    Hello Tom:
    No I meant restart the computer. OS X rebuilds preference files as needed, but I am not sure what it does if you do not restart.
    You could also reset Safari (that will also delete your cookies).
    Just for the heck of it I would also run permission repair and also run repair disk from your software install DVD (those will probably not fix anything, but it does not take much time either).

  • Intermittent proxy error "There is a problem with the proxy server's security certificate. Outlook is unable to connect to the proxy server "

    Hi all,
    From time to time (at least once a day), the following message pops up on the user's screen:
    "There is a problem with the proxy server's security certificate. Outlook is unable to connect to the proxy server . Error Code 80000000)."
    If we click "OK" it goes away and everything continues to work although sometimes Outlook disconnects. It is quite annoying...
    Any ideas?
    Thank you in advance

    Hi,
    For the security alert issue, I'd like to recommend you check the name in the alert windows, and confirm if the name is in your certificate.
    Additionally, to narrow down the cause, when the Outlook client cannot connect again, I recommand you firstly check the connectivity by using Test E-mail AutoConfiguration. For more information, you can refe to the following article:

  • Outlook is unable to connect to the proxy server.(Error Code 10)

    Hi,
    I had problems with RPC proxy, I was trying to setup cutover migration.
    So I read somewhere that i need to change the certprincipalname with Set-Outlookprovider.
    But after this change my outlook was not working anymore
    The settings before the change were:
    Name                          Server                        CertPrincipalName             TTL
    EXCH                                                                        
                 1
    EXPR                                                                        
                 1
    WEB                                                                          
                1
    So I set this back to the original (above) but this didn't helped...

    Hi,
    Please make sure the mail.abc-company.com is included in your Exchange certificate which has been assigned with IIS service.
    If possible, please run the following command for double check:
    Get-ExchangeCertificate | FL
    For Autodiscover service, please run
    Test E-mail AutoConfiguration to check if the connection is successful in Log tab and confirm the other services URL can use proper namespace in Results tab for request access.
    If the Autodiscover service fails, please create a SRV record with mail.abc-company.com for Autodiscover service to have a try:

  • Outlook is unable to connect to the proxy server. (Error code 0)

    Hello,
    I have just commenced a Exchange 2007 SP3 to Exchange 2013 SP1 migration following the following guide: http://blogs.technet.com/b/meamcs/archive/2013/07/25/part-1-step-by-step-exchange-2007-to-2013-migration.aspx
    As per the above guide, my 2007 environment is now known as legacy.company.com and my 2013, webmail.company.com.
    I'm using the same certificate on both boxes and it has the names autodiscover.company.com, webmail.company.com and legacy.company.com. All that seems to be working fine.
    OWA is functioning perfectly, hitting https://webmail.company.com will pass the user off to https://legacy.company.com if the mailbox is on 2007. Alongside this, Outlook also has no issues connecting to 2007 mailboxes with the client proxy settings
    being reconfigured to https://legacy.company.com automatically.
    My problem comes when a mailbox is migrated to 2013. OWA functions fine and presents the mailbox but Outlook is unable to connect, presenting the error:
    There is a problem with the proxy server's security certificate.
    The name on the security certificate is invalid or does not match the name of the target site webmail.company.com.
    Outlook is unable to connect to the proxy server. (Error Code 0)
    If I modify the Outlook client's settings and disable "Only connect to proxy servers that have this principal name in their certificate: msstd:webmail.company.com", Outlook connects and functions fine.
    I'm at a loss and have tried everything I can think and find on google. Any suggestions would be greatly appreciated.

    Hi,
    Please refer to the following article :
    http://support.microsoft.com/kb/923575
    Cause:
    This issue may occur if one or more of the following conditions are true:
    The connection to the  server requires a certification authority (CA).
    You have not trusted the certification authority at the root.
    The certificate may be invalid or revoked.
    The certificate does not match the name of the site.
    A third-party add-in is preventing access. 
    Solution:
    To examine the certificate, follow these steps:
    In Microsoft Internet Explorer, connect to the RPC server or to the secure server. For example, type
    https://www.<var>server_name</var>.com/rpc in the Address bar of the Web browser, and then press ENTER.
    Note The <var>server_name</var> placeholder references the RPC server name or the secure server name.
    Double-click the padlock icon that is located in the lower-right corner of the Web browser.
    Click the Details tab.
    Note the information in the following fields:
    Valid to
    The Valid to field indicates the date until which  the certificate is valid.
    Subject
    The data in the  Subject field should match the site name.
    Hope this helps!
    Thanks.

  • Safari Can't Connect to the Internet

    In an attempt to eliminate kernel panics after upgrading to 10.4.7, I removed two login items which were installed by Earthlink Total Access. After having done so, Safari can't connect to the server. I can run Mail, Foxfire and Moztlla.

    same here. Safari 3.0.4 opens perfectly well, checks .rss feeds and nothing seems to be wrong.
    but it does not do anything in terms of internet browsing. entering a url does not help, clicking on a bookmark does nothing either. if I click on a link from, say an e-mail safari opens but the screen stays white and the adress field empty.
    any ideas, I tried a forum search but could not find anything related but this topic.
    help is greatly appreciated!
