Republish Pages with Gitlab domain?

I unpublished my pages website with the Gitlab domain, but now i want to bring it back. When I go to the it goes to 404. I used to have a different tab in the Pages section that had the pages link, as if it was activated, but now I cannot find it or find a way to bring it back.

Please help, this is quite urgent. My link is being used in official websites that I no longer have access to. Thanks in advanced.
