WebSocket server logs are full with errors

I've enabled -verbose mode on the server and in the logs I can see many - a way too many - errors and fails, below is the output of journalctl -u outline -f | grep -iE "err|fail":

and it's keep coming and going.

What that means? Why it's failing to decrypt length and unpack so often? Why closed network connection might be happening (often enough, as well)?

Thanks in advance!

Don't think so - it's a pure WebSocket server.
