Anyone know why this is happening? Confused! I just tried favouriting or replying to a post from gts to masto, and this!

An error occurred while sending your toot. The reported problem was:

Server did not return an OK response code (403: Forbidden: you do not have permission to reply to this status)

No idea what is causing that, no settings on my end, so I assumed masto has updated something for interaction requests and now I can't interact. Some #FediHelp would be appreciated, or anyone who knows something about this, thanks in advance! Lots love! :)
