Unable to clone repository from GitLab to SourceTree


I’m trying to login to HiQ’s Gitlab from the application SourceTree and my access request got denied even though I can access GitLab from the web browser.

I tried several log in credential for the SourceTree however it did not resolve the problem. Does anyone know what is the problem?
I also have my SSH key saved, there isn’t any password for the project.

Is the project a publicly visible one that we can test?

Have you asked the administrator of that GitLab server for help?

Is the problem only in SourceTree (in which case you should ask them for help) or can you reproduce it on the same computer using the command line Git client or any other tool?
