We are experiencing random player disconnects on our Velocity proxy. The console shows the following error when it happens:

I initially reported this to ViaVersion, but a ViaVersion developer said the issue had been previously reported and seemed related to Floodgate.
I cannot confirm if it’s directly caused by Floodgate, but mentioning it in case it helps narrow down the cause.
