Console Error

NativeIoException: readAddress(..) failed: Connection reset by peer

That's literally all.

Bug Description

So, I've set up Viaversion, ViaBackwards, and ViaRewind on my 1.16.5 spigot server. Once I try connecting with 1.8.8 to that server, it gets weird from there. So the plugin works fine on my Lobby server, and I can connect to it normally, however, when I join the other server, the client is kicked displaying no errors at all. The only error I could find was on the bungeecord (waterfall) server, which is the one in the above field. I tried with ProtocolSupport, and it worked fine.

Steps to Reproduce

  1. Install ViaVersion, Backwards, And Rewind on a 1.16.5 Paper server.
  2. Connect to the server using a legacy version (1.8)
  3. ???
  4. Player crashes and sends an error in the bungeecord.

I can't exactly give good steps, since I'm not too sure what's causing it myself.

Expected Behavior

The legacy players should be able to connect to the server without crashing.

Additional Server Info

I use waterfall, with this list of plugins: Plugins (15): AntiBot, AntiVPN, BungeeHub, BuycraftX, CommandWhitelistBungee, DBVerifier, LuckPerms, NuVotifier, Parties, PartyAndFriends, RedirectPlus, ServerListPlus, ServerUtils, UltraStaffChat and nLogin

Checklist

Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both. I have included a ViaVersion dump. If applicable, I have included a paste (not a screenshot) of the error. I have tried a build from https://ci.viaversion.com/ and the issue still persists.

Try -dev builds from the ci, otherwise open an issue on the ViaRewind issue tracker.

Oh, yeah. Good point xD I confused the plugins a bit, sorry about that! Opened the issue there instead!
