Trouble signing in ArcGIS Pro (after accidentally hit sign out)

[PaalPedersen]

Hello everyone,

I am new to this community, and I hope this issue can be solved.

So yesterday I wanted to change my associated portal in ArcGIS Pro, and I hit sign out ( Instead of manage portals).

Then ArcGIS Pro froze, and I had to force kill the application. When I try to open ArcGIS Pro  I come to this window:

 

You can see right away something is odd with this window, but I try it anyway.

When I add my credentials I come to this window:

As you can see from the purple colors, I have tried everything here.

On the configure license options I have asserted correct settings:

I believe if I had a server registered with ArcGIS Pro Advanced licenses, I could do a Concurrent Use License, but my license is a Named User License. 

I then went to do a Geek unistall ArcGIS Pro, and do a fresh reinstall, without fixing the problem. Same problem persist.

Have anyone been in a similar situation?

From what I could find in the community was about some faulty webadapters. I don't know anything about webadapters, so I really didn't know how to troubleshoot that option.

What I have done is:

Make sure my user has the right privleges (ArcGIS Pro Advanced License).

What I would like to do is add this connection directly in some config file, if that is possible?

Or if anyone know what the problem is,  it would be really helpfull.

Thanks in advance!

Happy where too.

Thanks to our support team we manage to locate the problem.

My internet settings for security was set to high. So the system was partly blocking the connection.

changing the security settings to medium fixed my problem:
