Gitlab desktop client connect not found

How to Use GitLab
1

Hi, I would like to ask you for help, I’m just learning this world, I currently have a system that runs under docker swarm and portainer. I would like to run my own Gitlab for testing purposes, Gitlab’s online interface works perfectly, but if I try to connect to it from my own computer, for example a SourceTree, it cannot connect to gitlab. Unfortunately, neither HTTP nor SSL works. Could you possibly help me find out what I’m doing wrong and why it doesn’t work? Could it be that the SSH port of my server is 22222? I tried but unfortunately it didn’t work either.
Thank you in advance for your help.

Hi there,

Do you want the SSH for GitLab also to go though Traefik? In that case you should remove

ports:
      - "2222:22"

from GitLab config, and add it to the Traefik. Also, I believe the entry is wrong, because ports is <host>:<container>, and according to your current GitLab config, it should be 2222:2222.

But, I think this error you are getting is not because of ssh misconfiguration (although this one might come up later when cloning over SSH). As far as I understood - you can open WebUI (https) and try to login and it does not work? In that case, check that you are using default Admin (root) credentials for the first time. If you don’t have those anymore, then you can reset it by exec-ing into the GitLab’s container and use the Rails console.

Hope this helps! :slight_smile:
