Error: fatal: unable to access remote: The requested URL returned error: 403

I am having issues accessing a repository on gitlab. The issue seems related to the usage of Git LFS. I cannot fetch, pull or push without getting an error 403 or an authorization error.

Also, cloning seems to not work consistently, I sometimes get an error 403 when I try to clone any repository from gitlab. The issues started since yesterday. I have tried to do a clean install of SourceTree but the issue is still present.

I have also tried to clone and perform operations on the repositories of my team on gitlab through other git clients (i.e. GitHub Client and GitKraken) and everything seem to work fine, so I suppose it's something related to how SourceTree is configured.

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://gitlab.com/team/test.git
Output:

This error means that gitlab is not recognising your login/credentials/certificates.

In turn, that means you've probably not given the right details to Sourcetree.

[Panez]

Thanks for the reply, but i've already tried logging in with the same credentials on another pc and it works without errors.

[Nic Brough -Adaptavist-]

Ok, so there's a network problem between your first machine and the git server, or the git server is configured to refuse you access.

[Panez]

not sure about that. I've also tried logging in through Github Desktop and that seems to work.

[Nic Brough -Adaptavist-]

I am sure, you've got two computers that can connect and log in, and a third that can not.  The problem has to be something different in that third computer.   If it's similarly configured to the other two, then it has to be the network. If it is completely different, then its network settings are a problem.

[Panez]

First of all, thank you very much for your patience. Anyway, I didn't specify that github desktop is installed on the same machine where sourcetree is refusing to work. Do you think the problem is still network related?

[Nic Brough -Adaptavist-]

Yep, "same machine" is great for debugging, it rules out so... many... things, but not quite the network.  

Sourectree is going out over standard routes and ports, so the question now becomes "what is github desktop doing differently?")

@Panez  any luck?
Please if you solved this issue Please tell us how?

[Panez]

Hey, unfortunately no. I haven't solved it. No idea what caused it, Sorry.
