Failed to update secure chat state

[weiluntong]

Expected behavior

Chatting should just work, as my friends are all on vanilla clients without mods. I'm using Paper on the server for optimizations (vanilla kept giving me "can't keep up" messages despite having 1 or 2 players on at the time of testing), but I haven't installed any plugins or datapacks, and the vanilla clients have seemed to connect without any issues until yesterday.

Observed/Actual behavior

The first time I observed this behavior was yesterday, and I saw this in the logs:

However, at the time, the player had immediately greeted his friends (small server), and chat was working, so I assumed it might be an isolated incident that might resolve itself. Today, I see this:

Seemed that after that, they were speaking just fine. Initially they'd guessed swearing was banning their chat privileges, but the proceeded to test an extensive vocabulary of profanities, and the chat persisted.

Steps/models to reproduce

So because of the nature of the issue, I'm not sure how to reproduce it, as it's not even consistently banning chat as far as I can tell right now.
