Website keeps logging me out

I keep getting this error when using the website:-

Not Logged In

Please log in to see this page.

I even get it when I go to Mapillary cookie policy use

This started yesterday.

What browser are you using? Since last update, I cannot log in with Firefox, because one transaction behind the scenes (query loading the feed) gets blocked (NS_BINDING_ABORTED) and everything gets redirected to 404 page.
Everything works with Chrome.

I am using Brave Browser, which is based on Chromium
