Addressable::URI::InvalidURIError: Invalid port number: "GROUP"

This error happens if you specify https://gitlab.example.com:GROUP/PROJECT.git as the URL at mirror page. This can happen by accident if you, for example, just copy the project URL from the project page.

If we have a malformed URL, we should not see 500 page.

moved from gitlab-ce#28053

added mirror label

I am also facing this issue: https://sentry.gitlap.com/gitlab/gitlabcom/issues/46422/

This will be resolved by https://gitlab.com/gitlab-org/gitlab-ce/issues/37448

In the meantime, simply ensure you use a valid URL.
