Problem to solve

I have Terraform enterprise integrated with Gitlab community edition, this gitlab is configured as VCS repository on Terraform, and it was working fine in 2 environments.
suddenly I noticed that when I need to create new workspace in terraform as VCS workflow, it failed as it is not able to fetch the repo and templates from gitlab, although the connectivity is available and nothing is changed in the environment

Steps to reproduce

Create a new workspace in Terraform from VCS

Configuration

Provide screenshots from the GitLab UI showing relevant configuration, if applicable.
On self-managed instances, add the relevant configuration settings or changes.

Versions
