    Oh wow, THANK YOU for saying that you could connect using I didn't think of that, and it's helped me get past this error at work. I LOVE YOU – clamum Jan 26 '17 at 21:16

You should add http:// before localhost:port for IE. Unlike other browsers, IE needs to know what protocol is being used.

  • Are you sure? I just tried typing only localhost and IE turned it to http://localhost/ .. – Bibhas Jan 31 '12 at 19:06

    Good habit is to include the protocol first; however if it is just localhost and no actual port number, you can usually just do what you stated and type localhost without issue. If you need port numbers though, you should used the proper protocol format. – zackrspv Feb 1 '12 at 0:58

Some things to try:

  • try adding the port to localhost: localhost:80 or localhost:8080

  • try checking proxy bypass settings for Internet Explorer (Tools -> Options), make sure it's set to proxy bypass for localhost

  • Check C:\windows\system32\drivers\etc\hosts and make sure the localhost entry is there

    Under Windows 7, hosts no longer contains an entry for localhost (this is mentioned in the comments). – Richard Jan 17 '10 at 9:37

  • localhost still works in Win7 for me, using the latest IE. – cutrightjm Jan 31 '12 at 17:40

Old thread, but I thought this may help someone.

Windows 7 Pro / IE 11

I had the exact same issue (http://localhost works in Chrome, and worked in IE too). Tried various things like updating hosts file entry, disable ipv6 in network settings etc.. nothing worked.

Finally fixed by adding http://localhost to trusted site in IE Settings Internet Options>Security>Trusted sites. Make sure to un check the "Require Server verification (https).. " option when adding the trusted site address.


If your local host uses default port(i.e 80) then it will resolve . If it uses different port then you will have to specify the protocol.


In my case, it is because there some add-ons that always go to search engine when I browse to my localhost. So I just disable this add-ons in Tools > Manage Add-ons > Click Search Provider > Set Default to Bing,

and my problem is gone.
