Errors while connecting to TFS (hosted)

Hello,

I am trying out Rider on my existing solution which is using an on premise TFS as source control.

Sadly, this is not recognized by Rider out of the box, so looked up some posts here, downloaded tf.cmd etc.

Based on the steps below, I got to 'Reload workspaces' (I see my project collection and a workspace) - but I get an error:

https://rider-support.jetbrains.com/hc/en-us/articles/360000335099-How-to-use-Visual-Studio-s-TFV%D0%A1-local-workspace-in-Rider

Hitting edit info shows this 'authInfo' error box.

When I try to view file history, I get this

13:50 Problems while loading file history: HTTP 401 Unauthorized

What should I do to make it work?

THanks

Bartosz
