Gitlab integration - problem with connection

I have some problem with gitlab integration.
When I’m trying to create a configuration (name, api url and personal acess token) I get message “Could not validate GitLab url. Got an unexpected answer.”
In the log file i found informations such “No route to host: no further information” and “Failed to connect”.
There is no problem to connect form machine where SQ is installed to GL machine. I can connect from SQ machine to GL via ssh, i can send requests via curl or postman, i can pull the repo etc.
What could be wrong? any hints?


Welcome to the community!

What port is GitLab at? Is it possible that port is “helpfully” blocked? (E.G. by Iptables).
