Azure DevOps - Git unauthorized after moved to other tenant

Holger Vetter devops, .NET, C#, Azure, git

I worked on a git repository hosted in Azure DevOps. Everything worked fine, until the DevOps was moved to another tenant.
Now my git repository was broken (Authentication failed).

I deleted the whole local repository and tried to get it again.
But every time I tried to clone it, git opened the wrong tenant login view (the old one). Instead of showing the login view for the new tenant.

Here is the log produced by the git clone command.

I tried to delete the Cache, erase the CredentialManager from git, logout in VisualStudio and so on...but nothing worked.

Solution

The solution was to delete the Credentials for this DevOps from the Windows Credential Manager. Then I cloned the project again and the correct tenant login view appeared.
