Windows/Firefox fail to log in

[disconsented]

Describe the bug
Trying to log in to the client with Firefox as the default browser, OpenID connect consent is successfully given, and we get redirected to something like http://127.0.0.1:64351/?code=NXq-MmI7GkHYWyi7KAVKa3sqoc102bTWmvTRUNCATED&scope=openid+offline+public_profile+upload_map+upload_mod+lobby&state=YqWppNPOzAQsoyJ8wU0OOGrlbSTRUNCATED, where the client then reports what's below.

This doesn't happen in edge, so I assume it's a Windows/FF specific issue.

Log or error message

Cant reproduce on FF with Linux

Does the URL really contain http:// or https://? Because it looks like encrypted data being sent to an HTTP port.

Browsers may redirect you to HTTPS if you ever visited a website via HTTPS. Google HSTS. AFAIK, Chrome only does this for hostnames, not IP-Adresses, but I'm not sure about this and I don't know what Firefox does. Try deleting HSTS for 127.0.0.1 (or localhost) in Firefox

Hmmm yeah I guess that would explain the characters. I guess I never really expected browsers to redirect localhost to https since I thought the server normally controlled the redirects.

[Brutus5000]

If this is the case it's kind of a no-win scenario. Even if we offer https the browser will complain because we can't offer a valid certificate...

Yep, my browser was going to HTTPS first due to the Smart HTTPS plugin, disable that, and it all works fine.
