Can't clone from Azure DevOps

[brendan_cockman]

I cannot clone an Azure DevOps repository for source tree through the UI. I can clone through the terminal, but even after adding the local repositorey to sourcetree it fails.

I have also tried using a PAT and crfeating a remote account - the account is added fine and I can browse repositories but when I select Clone I get the same error: Access is denied.

Why is access denied when it's already authenticated using PAT?
If I copy git the comand in the error screen into the terminal it works fine - only fails in the UI (latest version 3.4.15).

I have tried clearing credentials, deleting accounts, re-installing source tree, using embedded and system git. All fail with the same problem.

Other clients (git fork, visual studio and vs-code) all clone with no problems, but I am more familiar with sourcetree. Any help would be appreciated
