Which service are you trying to connect to

• [ ] Azure DevOps
• [X] Azure DevOps Server (TFS/on-prem)
• [ ] GitHub
• [ ] GitHub Enterprise
• [ ] Bitbucket
• [ ] Other? - please describe;

If AzureDevops Hosted describe your url

• [ ] dev.azure.com/org
• [ ] org.visualstudio.com

If you're using Azure DevOps, can you access the repository in the browser via the same URL?

• [X] Yes
• [ ] No, I get a permission error.
• [ ] No, for a different reason:

If you're using Azure DevOps, and the account picker shows more than one identity as you authenticate, check that you selected the same one that has access on the web.

• [X] I only see one identity.
• [ ] I checked each and none worked.

Expected behavior Credential Manager pops up and asks me for credentials. Or Credential manager uses credentials I saved in Credential Manager for that URL

Actual behavior No popups when I run git clone http://...

Set the env variables GCM_TRACE=1 and GIT_TRACE=1 and run your git command. Redact any private information and attach the log

• I renamed my local user from Andrew to Andre so it doesn't try to use localMachineName\Andrew as a user Id

It looks like the server is trying to use NTLM and failing. I would talk to your TFS administrator about the auth setup here.

In the meantime, you can turn your GCM to basic authentication using the following commands:

• Run “git config --global credential.authority Basic” this should move you to basic auth
• You should now get a popup that says “Git Credential Manager for Windows” across the top and lets you fill in username/password

If your username/password don't work here, a PAT entered as username will.

I'm my TFS administrator. I purchased basic version.

@jeschu1 Please talk to me :)

BTW, there is one more problem, I can't login to web UI anymore from emote desktop. It asks for the basic auth and declines.

The same credentials works just fine on local computer.

I do not want to switch global git credentials to basic auth. I use ssh, but been unable to login to web UI is a killer.

@v-andrew, ssh is definitely a great choice for communicating with TFS. That doesn't use GCM, but it's a recommended option.

TFS support is your best option for the Web UI. They should be able to help you with any connectivity issues there.
