Actions to reproduce (if known)

Unknown. I ask each time players get kicked; one time they were chopping a tree, another time being idle - seems unrelated to any activity. They do all have wireless connections I've found so far, so could be packet-loss and keep-alive related.

Paper version

Current: git-Purpur-1995 (MC: 1.20.1)* Previous: git-Paper-26 (MC: 1.20.1)

(only using Purpur for the keep-alive option for patchy connections ironically)

Other

Error on bungee when player disconnected (with message 'server went down', which it didn't): "DownstreamBridge <-> [Survival] - NativeIoException: recvAddress(..) failed: Connection reset by peer"

Spark profile: https://spark.lucko.me/ngRIAJ13HV

I don't know if the stack trace I posted is related to the kick for this particular player, because for another there was no such issue with permissionsex.

Seems like PermissionsEx problem to me. Please, consider migrating to some actually supported plugin, like LuckPerms.

I shouldn't have included that stack trace - he's the only player who gets disconnected with that stack trace. I don't think it's PEx.

That error is not the cause, it won’t cause a disconnect; we don’t accept reports from software that isn’t ours, nor is this the place for support, all we can tell you is that the connection between the proxy and the server was closed in an unexpected manner, you’d need to see if there’s any more in your logs which might be useful, or start looking into network diagnosis
