Are you using Cloudflare DNS (1.1.1.1) by chance? Today I basically couldn't get the site to load at all. I thought it was down or at least a general problem. But just to test it I switched do a different DNS and now it is working fine.
I thought about doing that, but no. I mean, what would I say? If I could remember the mail address I would, but that was just a "fake" temp one I used - otherwise I obviously could just reset the password. The only thing I know is the username and that is public lmao.
