Ublock extra is also a problem.
Earlier, some other extensions were failing, but I was able to install them after I re-installed brave.
I can’t find a pattern.
Your status page stays things are fine.

Usually, I just install extensions from the chrome extensions store… never seen the url…

Same here. Brave seems to intercept the URL and use its own repos.

Do you have developer mode enabled in Settings --> Extensions?

I did not. I just tried with it enabled and it didn’t change anything.

Just tried the URL from a Tor backed private window and it downloads, so it seems my normal IP is in a blocked range.
Would be useful to have a more meaningful error message. The current one makes it sound like the Brave infrastructure is having an issue.
