Pull or push timeout


I have my gitlab server working well. I can push ,pull and clone without issue.

But i have one server from this one i can4t pull or push to my gitlabserver everytime timeout. Before it was working well.

Is there any ban ip or ban systeme on the gitlab server . My gitlab server is gitlab-ee-11.0.3.

I can pull or push from all the server but only one can’t and each time timeout

Best regards
