Windows – Microsoft Edge can not display local web site

microsoft-edgewindows 10

I have a local IIS running, with a binding like www.dev.mydomain.com, the hostname is listed in an external DNS server and name resolution works fine.

When opening the site http://www.dev.mydomain.com in Microsoft Edge I get this message:

Hmm, we can't reach this page.

Make sure that you’ve got the right web address: http://www.dev.mydomain.com

The F12 Network Tab doesn't show anything.

What does work:

  • Using Firefox, Chrome, IE-11 and Command Line tools on the local machine
  • Using Edge from another machine on the local network
  • Using Edge on the same machine but with a different user
  • Using Edge with my user but using localhost or an IP address either 127.0.0.1 or 192.168.x.x

What I tried but not solving the problem:

  • Restarting the Network List Service and the Network Location Awareness service.
  • adding www.dev.mydomain.com to the hosts file.
  • using TLS and https://www.dev.mydomain.com
  • Using the same Windows Proxy settings as for the user which doesn't have the problem.

So this is a problem specific to one user and Edge, other programs or users don't have this problem.

Any ideas what else I can do to diagnose this?

Windows 10 - 1607 (14393.105)

You need to enable the loopback address which is disabled by default in edge.

go to about:flagsand enable "allow local loopback"

be aware that there is a security implication in this but the risk is low.
