When I first add a repo, it shows Active. Then after a short time, it gets stuck on Git Updating. The repo url is to an externally facing GitLab instance. The repo has a deploy key with write access and I've confirmed that this key does indeed work. It does not have a passphrase. If there is a connectivity issue between fleet and this external GitLab, would that cause the Clusters Ready column to show 0/0 and No clusters available?
