Note that this only happens with Brave, both with and without the shield. The pages open every time on Chrome, Edge, Opera, Firefox, and Firefox Developer.
I tried in private mode WITHOUT disabling extensions, and that got me in.
So back to “regular” (non-private) mode…
There were no cookies (apart from PHPSESSID), I deleted that one, but no difference.
I have tried deleting cache. Never been sure how this works. I find the page listed in history, delete x hours, still won’t let me in. Then deleted a week, and that still doesn’t appear to make a difference either.
If I have the page listed in history, and checked, is it just deleting cache for that page, or for all pages? And how far should I go back? I use this page most days.
by default when in private mode it disable extension but i asked you to disable extension to make sure it off
so try to disable all extension in normal mode and see if it help
if it work then reneable them one by one till you get the one cause the issue
try the extension first
since you use it usualy then try to click on the lock icon on the left of the address bar then you can clear the cache there but only after try extension
