XE error - "can't establish a connection to the server at 127.0.0.1:8080"

I installed XE on my laptop, os windows xp prof. v2002 sp2.
Database works fine, I can access with sql command line.
But can not access to database home page and apex.
Tried both links with both IE and Firefox;
http://localhost:8080/apex
http://127.0.0.1:8080/apex
Same error I get; "can't establish a connection to the server at 127.0.0.1:8080."

Using oracle (services in manual) following message appears Firefox can't establish a connection to the server at localhost:1158.

when I use oracle 11 and have it set in automatic (in services) it operates properly. (after restart) When I have it in manual (in services) i get the message 'Firefox can't establish a connection to the server at localhost:1158.'
We use the computer for various instructors but only one uses Oracle. With oracle in auto it takes for ever to log in (2 mins or more), when it is in manual it takes 10 secs for log in.

you mean the local.profile?
i have the next values
export ORACLE_BASE=/export/home/oracle
export ORACLE_HOME=/export/home/oracle/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=XXX
export ORACLE_TERM=xterm

& All Matches with the path of the installations of oracle & java
thanks in advance

Windows performed an automatic update. I am now unable to use Firefox. I receive an error message "Firefox can't establish a connection to the server". Windows IE works, Outlook works. What did Microsoft do to me this time?!!!

Windows performed an automatic update on my PC this morning. Now, Firefox does not work other than in SAFE mode. I get "Firefox can't establish a connection to the server..." I downloaded and reinstalled the latest version of Firefox and get the same error message. IE works. MS Outlook works. What did Windows do to me this time?

You can find the connection settings in Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.
See "Firefox connection settings":
* https://support.mozilla.com/kb/Firefox+cannot+load+websites+but+other+programs+can
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Unable to connect Firefox can't establish a connection to the server at 'URL of the site' why does this appear in all browser??

I have used these sites
-www.facebook.com
-www.dubbedonline.tv/ and some others for a long time but few weeks ago i couldn't access them anymore and this appeared :
Unable to connect
Firefox can't establish a connection to the server at www.facebook.com.
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.
i have also tried many ways to access them but none of the solution worked, one of them was checking troubleshooting problems and it detected that the remote device won't accept the connection, so, how can i fix this?

Firefox can't establish a connection to the server at "Every Website" but IE and Safari work just fine.

Unable to connect
Firefox can't establish a connection to the server at google.com.

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.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

If you get the same problems with two browsers, the problem is
outside of them. Check you computer for blocking programs.

Im trying to set up a connection to localhost from my mac but keep getting an error message: Firefox can't establish a connection to the server at localhost.

Hi
I'm new to working with Mamp, Dreamweaver and WordPress and am trying to work using the Firefox browser. unfortunately i keep getting the error message Firefox can't establish a connection to the server at localhost. when i type the URL http://localhost/explore_ca/blog/wp-admin I cant use Dreamweaver with WP without this is there a reason for this and how do i get around it?

1- Is your MAMP working '''whithout errors'''(does it show you errors while executing or running and enabling)?
2- Have you tested other browsers? Is your problem still occuring?
3- Are you using '''proxy '''or '''VPN '''(or setted a proxy server or VPN server on your Computer)?

Firefox can't establish a connection to the server at localhost

I was building a wordpress website on my PC: using Firefox browser, accessing wordpress through WebMatrix which opened Firefox & showed a 'localhost:20238' address. It worked for 5 days then WebMatrix said ' website does not exist. I could still load it for 1 day using browser history. Then that failed too. Have ditched WebMatrix. Now loaded XAMPP & Wordpress (shown as succesful). Putting 'localhost' into address box. Error message: Firefox can't establish a connection to the server at localhost.

Does it work in other browsers?
When you enter http://localhost/ Firefox will try port 80, since that is the standard for web servers. If there is any other software on your computer listening on port 80, the web server might not be able to use it. Can you check your XAMPP settings and try using a different port such as 8080? Then you would access the server using http://localhost:8080/.

Have an error saying 'Firefox can't establish a connection to the server at localhost:50972. '

I bought a product called 'Helium Music Streamer' and downloaded it. I registered the product and went to launch it..
only it wouldnt launch.
It had the error 'Firefox can't establish a connection to the server at localhost:50972.'
I would be glad for some help

Hi, in case you haven't solved your problem - here's what i've discovered based on having same issue. where IE proxy system settings automatically allows local host url access; It appears FF system proxy or auto-detect does not, it's settings blocks local host URL access. To access local host, "no proxy" settings should allow or, only way to allow this exception (or any other exceptions) is through their manual settings. You should see in manual settings that the local host is already set to be allowed through.
FF also has plug-ins available which allows you to configure multiple proxy settings/profiles that you can toggle between based on your connection needs. THis way, when you want to use local host you can select it's proxy profile and go back to default proxy settings for regular web surfing, etc
Hope this helps you.

Hello
I have installed N1 system manager but when i try to open its web page there is an error occur on web page which is i paste below. Any body help me. please i shell be thank full to u.
Firefox can't establish a connection to the server at 192.168.50.28:6789

The error you're saying suggests, that your N1SM isn't either configured or didn't start up properly.
N1SM was EOLed (end of life) long time ago & doesn't support any newer systems or S10 updates
Also it's slowly nearing EOSL (end of supported life).
N1SM was replaced by xVM Ops Center, which was released as of version 2.0 two weeks ago.
I strongly suggest you ask your local Sun representative for xVMOC and disregard N1SM.

Firefox can't establish a connection to the server at any website I visit yet internet explorer is working fine.

I have tried uninstalling firefox and reinstalling it and it's still not working. Why won't it establish a connection all of a sudden? I'm browsing using internet explorer just fine, but I want to use firefox.

Thank you so much for the link, Gryllida! Selecting "restore defaults" on my McAfee firewall was the key! Thanks again! ~stacy
