Similar issue to one I have been experiencing in a Private TOR tab (already a separate thread for that), but this time it’s in a regular Private tab and the webpage is the main Brave Community webpage (community.brave.com).
On the second try, in a separate tab, the page loaded normally.
Hopefully just a fluke.
