I tried to DM a Lemmy user. This URL was associated to the mail icon:
https://fedia.io/u/@[email protected]/message
That gives a 403 forbidden. I use Tor but neither fedia nor discuss.tchncs.de are tor-hostile. So I doubt Tor is related.
I have to say apart from the above issue, fedia has been working smoothly lately. I’m glad the internal server errors that plagued the system have apparently been resolved AFAICT.
It works. Thanks!
