Two of my repositories are now inexplicably failing Repo Sync’s.
Could anybody assist in what do I do to fix this?
You might be affected by this issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/59053
this means if a user attempts to import enough repositories, mirroring will fail for some repositories.
Our engineer suggested a workaround:
Workaround: Go into the Repository settings, delete the pull mirror, and re-add credentials with a personal access token.
Hopefully that helps.
