I'm using the preview Extension for TFVC / TFS support (v 0.1.1) in VS 4 Mac (188.8.131.521). I followed the instructions at https://docs.microsoft.com/en-us/visualstudio/mac/tf-version-control. I can connect to VSTS just fine. When I try to connect to my on-prem TFS, it just spins at the "connecting" / "choose projects" phase after entering the data - nothing ever happens. My TFS has a public url only via https. I understand this was just released but are there any tips or ways to troubleshoot? Has anyone gotten this to work with an on-prem TFS?
