I have a very old repo I want to get at again, it seems archived and inaccessible

Its been a while, a decade in fact, big life changes and stuff, but I want to come back to a project and the code and assets have all vanished and seem to have been archived. When I go to the old URL

(https://SpaceMammoth@bitbucket.org/SpaceMammoth/mammothgravitybattles.git)

I get the following with a circle animation that never finishes:

Its been a while, I can't complain that my stuff has been archived, but I'd love to get it back. the link there claims admins have a self service tool to un-archive - but I cant find it and there seems to be no way to contact support. Am I out of luck?
