Gitlab runner fails with connection timeout I have gitlab runner with, docker as executor and docker:latest as default image.
Runner is connected to the project and runs pipeline, but it stuck at

Reinitialized existing Git repository in /builds/sachith/omy-project/.git/
fatal: unable to access 'https://gitlab.myhost.com:1234/sachith/omy-project.git/': Failed to connect to gitlab.myhost.com port 1234: Operation timed out

I logged to gitlab-runner running server and tried cloning project as gitlab-runner user and it worked.
Why am I getting this error?
This is likely because your requests were dropped before they landed on the GitLab host. Check your firewalls and other security rules after assured that the 1234 port is open
