In the same time, I have an instance running in Safari and all behave the same. I checked in depth the gitlab.rb file and I do not have such redirection in place. Any hints or help is welcomed.

Now even more weird it that the whole website now redirects to gitlab.com . so whenever i try to reach out https://gitlab.uhlhost.net/ I get now sent to gitlab.com .

After making an upgrade and doing a git-rack:check it seems I can go now to the site, yet still main issue remains, I get redirected to uhlhosting.ch from / of gitlab.uhlhost.net. Anyone any idea?
