In the console, I can see submitting under them doesn't even produce network traffic. They also don't display properly with an @, which makes me wonder if their address is being stored wrong internally and making calls fail.
Is this a Lemmy issue, or could it be instance-specific?
Last time I checked, they were using DDOS Protection from Cloudflare which breaks all federation with them. Until that stops, it will not work.
That was fixed some time in the last 24 hours. I can see them now, and they can talk to me, I just can't talk back.
Ah my mistake, I did not know that change was made.
It's working again, at least for me. Not sure when they made the change but I can sub to kbin magazines and look at user profiles now.
