404 page for project not found

I am added to a private project as a maintainer and I already committed some files to the repo.
Yet for some reason I cannot not find the project anymore and if I click on the invitation-link that I received through email I only get a 404 page…
I asked the admin and he said that the project is still there and that I am still added to it.
Do you have any idea what could be going on?


I missed something, didn’t I?))
