After you mentioned this to me last week, I "shouted" a test message and got a reply from Tafial. And then tonight, the shoutbox has a convo in it with Luc, Josh and Adam talking about music stuff.
I just had a quick check and loaded up Witt on Microsoft Edge and it doesn't work on that. It seems to work on Chrome fine though. I'm nearly sure that you use Firefox, Miestra? So, it's possibly a browser related issue.
Thing is, the discord embed is highly temperamental. I have seen it go down and bug out from time to time.
Although, with Witt being Chancery controlled I don't actually have access to the right dashboards to investigate the probs.
(If it were up to me, I would just remove the Discord embed from Witt and install a regular shoutbox plugin specific to SMF. SMFPacks Shoutbox or similar appears to be what would work for us there. The Discord thing is a really nice idea, but it has never really integrated with Witt properly for everybody. I wouldn't bin the Discord completely though; I would have the Discord embedded on a regular webpage on Talossa.com instead, just not on the forums - easier to fix and maintain).
