Azure DevOps Server (earlier called TFS) - Problem adding remote account

[egisan3]

We have a setup with Azure DevOps Server 2019 (TFS) in our network.

I am trying to setup an account in SourceTree in the same way as described for the case (which refers to connection to Azure DevOps Service/VSTS) discussed here:

https://jira.atlassian.com/browse/SRCTREEWIN-10800?workflowName=SourceTree+Bug+Workflow&stepId=8&_ga=2.218138911.788638929.1598390300-269868521.1598390300

But the authentication fails every time.

Does SourceTree support authentication towards a Git server hosted by an "on prems" setup of Azure DevOps as we have?

What is the procedure to follow here?

Thanks
