The authentication process for Capture One Pro at startup does not work anymore

I am a happy user of Capture One Pro 22 and suddenly I am not able to start the program anymore.

Even after reinstalling it I cannot get it to work. This is where I get the error.

https://id.captureone.com/tfp/captureoneprod.onmicrosoft.com/b2c_1a_desktop_v6_signup_signin/oauth2/v2.0/authorize?

The error massage state. 

This page is not reachable 127.0.0.1 refuses to connect.

Have checked the proxy setting which is at automatic and added captureone.exe to the allowed list of the firewall.

This is suddenly happening to me after many years of eventfree use.

Does anyone have knowledge on how to resolve this?
