Since a few weeks, I’m experiencing some issues with my Visual Studio.
One of the symptoms is that I cannot re-authenticate my Azure account.
It’s timing out somewhere
I was able to find some logs but they said the same thing.

Another sympton is that VS.Net is popping up login screen (I use system web browser) pretty frequently. I don’t know why or what.
And final sympton is when I try to do a build, it’s stuck on Build started, pops the login screen 2 to 3 times (appearing time 30s and re-appearing time several minutes) for then to fail with this error : TF30063: You are not authorized to access dev.azure.com
If this happens, I can’t connect to my Git repo via Team Explorer either, it’s stuck on ‘Connecting’
Most of the times a reboot does the trick but it’s getting more frequent (multiple times a day) and it’s driving me crazy 🙁
Ironically enough when I try to use the ‘Report a problem’ method in VS.Net, it opens a new browser tab and then remains blocked on Authentication
I’m on the latest available version of VS.Net2022 Community Edition
Any Idea’s?
