Unable to view branches on forked repo

I’m unable to view the list of available branches of a project I’ve forked on gitlab.com .
Pressing the ‘Branches’ button on the sidebar gives me this error after loading for several seconds:

## Unable to load branches

The git server, Gitaly, is not available at this time. Please contact your administrator.

Clicking on the git revision dropdown selector loads a few tags, and then says ‘An error occurred while fetching branches. Retry the search.’

I can push to the branch, and even see it if I manually enter the right URL. ( https://gitlab.com/guerrera.nicola/linux-nabu/-/tree/ark-vanilla-mainline )
I also tried deleting and reforking the repository with no success. Any help is appreciated
