Answer 1

You may try the following items:

1. Go to Control Panel -- Credential Manager, and remove all Windows Credentials related to TFS.
2. Close all Visual Studio instances, delete %LOCALAPPDATA%.IdentityService if it exists.
3. Clear TFS caches %LOCALAPPDATA%\Microsoft\Team Foundation\x.0\Cache
4. As @4c74356b41 mentioned, repair VS.

Answer 2

As stated above, try doing only this step and see if it fixes the problem. It did for me.

• Close all Visual Studio instances, delete %LOCALAPPDATA%.IdentityService if it exists.

It saves doing all the other steps.

Answer 3

The same issue is still occurring in 2021. I had tried the sign out/sign in method, I had tried the local app data deletion method. No luck with either.

What worked for me were the following steps.

• Click on your name in the top right corner of Visual Studio and select Account Settings
• Now rather than signing out, look below this to the All Accounts section. On some it will say "We need to refresh the credentials for this account"
• Re-enter your credentials here.

This fixed the issue for me. I hope this helps someone else with this annoying issue.

Answer 4

Much easier solution to this. Close any open visual studio instances, restart visual studio as an administrator and connect to your ADO instance, i got this issue on cloning a repo personally, when i re-tried cloning again via web ADO the next time VS opened it worked just fine.
