I can't access My project on gitlab.com

Like this:https://youtu.be/7oE2GIZ-LqM
It is 500 error.

It might be a good idea to link to your project directly instead of expecting people to watch a YouTube video.

As it is, I managed to spot your username in the clone URL box, and the URL in the status bar, but really you should make these things easier.

However, I can’t access your profile or repositories (they’re private) so can’t help. You might need to file a ticket.

Ok, I will use ticket.
Thank you for your suggest.
