Grant Access - Register GitLab Application - 504 Client Timeout

Dear Xcode cloud support.

on 30.1.2026 Xcode cloud was not able to connect to our git server. so I deleted the repository from app store connect Xcode cloud settings and deleted the Xcode cloud in app store connect for all our apps. I started to create Xcode cloud workflow from Xcode and when I want to Grant Access - Register GitLab Application - to our git repository I get and error :

"504 Client Timeout. If you are using a firewall, it must be configured to accept incoming connections."

git is behind VPN but the IP address ranges 17.58.0.0/18, 17.58.192.0/18, and 57.103.0.0/22 are white labeled and before 30.1.2026 it was working.

I contacted the gitlab administrators and they acknowledged that during "Register GitLab Application" they see no traffic (in gltlab and proxy server) from xcode cloud. I tried "Register GitLab Application" multiple times until now with same error. It is not app specific because this error happens for all our apps.

Thanks a lot yours sincerely,

Zoltan Bognar
