Localhost not working in chrome and firefox

Question

I am doing a web project using visual studio 2010(MVC3 Razor) and Windows 7.

My default browser is IE. When I run the project, the website working is perfectly with the url

When I copy the same url and try to run the website in Chrome or Firefox it shows me the following error.

ERROR

The requested URL could not be retrieved    
The following error was encountered while trying to retrieve the URL: http://localhost:49824/    
Connection to 127.0.0.1 failed.    
The system returned: (111) Connection refused    
The remote host or network may be down. Please try the request again.    
Your cache administrator is webmaster.

I have rebuilt the solution and added the url to allowed site. But still the problem persists. How should I solve this problem?

Finally I found the solution ... It's very easy

Go to the LAN settings (In Chrome : Tools -> Options -> Under the hood -> Change Proxy setting -> LAN Setting)
There will be a checkbox for "Bypass proxy server for local address"
Tick the checkbox.

Done!

On Mac/Apple: Chrome uses system preferences for localhost exclusion:

Go to System Preferences -> Network -> advanced -> Proxy settings
Add 'localhost' at the bottom where it says: 'ignore proxy settings for these hosts and domains' (Exceptions are separated by a comma)

about:config > set "browser.urlbar.trimURLs" to false worked for me. – Tom Aug 26 '13 at 19:46

IN FF, under advanced, network, settings, change proxy to manual (you'll have to know what your proxy details are), and then add 127.0.0.1 to the "no proxy for" list. – Relequestual Dec 10 '14 at 11:16
Worked for me as well!! Thanks a lot!! – Mauro Bilotti Feb 02 '17 at 14:20
This guide is heavily out of date and is not reflective of the current situation anymore with Chrome. – Code Doggo May 25 '21 at 01:14

For all browsers,

Open internet Options (or Internet properties)
Go to connections tab
Click on LAN Settings
Tick Use proxy server for your LAN
Tick Bypass proxy server for your local address (Don't change the port number)
Click on Ok

Now you are good to go. :)

Proxy settings are no longer controled in Chrome it seems like. I can't find this option anymore and searching for "Proxy" in the chrome settings just opens up the Windows proxy settings from Settings app. – Code Doggo May 25 '21 at 01:14

I faced the same issue and the complete solution is to set to false(uncheck) the "Automatically detect settings" checkbox from Lan Area Network( the same window as for Bypass proxy server for local address )

If you are using windows system:

please check the file

C:\Windows\System32\drivers\etc\hosts

and add line such as:

127.0.0.1 localhost

While this should work, it seems like it is masking over a larger issue – Jon Onstott Mar 02 '15 at 21:34

For Chrome go to

Settings->Network->Change Proxy setting

Now Internet properties will open so you need to go LAN settings and click on check box :

Bypass proxy server for local address

Chrome uses your local internet settings. So go to Internet Options > Connections > Lan Settings - and click Bypass Proxy Server. – Joshua Duxbury Jan 13 '17 at 16:45

Changing my LAN network settings to not automatically detect a proxy server worked for me BUT resetting your Windows network stack may help.

In case the browser LAN proxy setting solution doesn't work for you:

As mentioned in this similar Q&A How to solve ERR_CONNECTION_REFUSED when trying to connect to localhost running IISExpress - Error 502 (Cannot debug from Visual Studio)?

Simply changing the port number of your web project can be a quick fix.

For Firefox:

Go to LAN Settings: Options->Advanced->Network. In the "Connection" section of the "Network" tab press "Settings" button to open "Connection Settings" dialog box.
Select "Manual proxy configuration:" radio button
The "No proxy for:" textbox should contain the following text: "localhost, 127.0.0.1"

For my project, I am set up to use https. I just got a new computer and cloned the project in git. The protocol and port number for the project are not saved in the solution file, so you have to make sure to set it again.

I found that when I had this issue that I had to delete the application.config file from my solution. I was pulling the code from co-worker's repository whose config file was mapping to their local computer resources (and not my own). In addition to that, I had to create a new virtual directory as explained in the previous answers.
