I set up a virtual Linux server via Hyper V on my Windows server and installed a Minecraft Bungeecord server there.
The bungeecord server is shown to me at MC when I ping it… But the sub-server does not and the console (when pinging once) always produces the same error code (and it does not end):
13:28:09] [Netty Epoll Server IO # 0 / WARN]: An exceptionCaught () event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.

And when trying to connect via Bungeecord this error message comes up in Minecraft:
Exception Connecting: NativeIoException: readAddress (.) Failed: Connection reset by peer
and in the console of the sub-server the mentioned error code (see above, first script).
Everything is configured correctly. I even tested it locally and via the Windows Server system, then it works.
With the bungee record everything is displayed correctly when pinged (MOTD, number of players, etc.), with the direct connection he does not find the server at all and shows as soon as he tries to ping the server the repetitive error code in the console.
Funny thing is that it shows bungeecord when you connect, but the forwarding and the direct connection do not work.
Knows who the problem is and how to fix it.
Do you have ProtocolLib installed? Which Java version do you use? Can you send your server.properties in here?
No I didn't install ProtocolLib…
My Java version:
openjdk version "11.0.6" 2020-01-14

Do it: motd = "Test Lobby"
If that doesn't help:
enable-query = false
And add: query.port = 25575
Can you please send your bungeecord config here?
Okay I'll try that first…
Here is the bungeecord config:

I have more under server, so I shortened the config and accidentally now here is the port 25577 in the address… In the unabridged version, that's correct.
If you try this with query, you would of course also have to set it to true in the Bungeecord config. I would also use local IP instead of localhost. You can often use 0.0.0.0 for the sub-servers.
Unfortunately it doesn't work… But thanks anyway.
I have no problem with the forwarding of BungeeCord to the sub-server, it is more about that if I ping the sub-server or a MC server in general or connect to it, regardless of whether it is forwarded via BungeeCord or via direct connection, this error message is generated and I'm not able to contact me can connect. But that's only on the virtual server (Hyper V) on my Windows server. It works on my computer or the server itself but not on the virtual Linux server that I set up with Hyper V.
I suspect that something is blocking the connection, but I don't know what and how to fix it. But maybe. But is it also technical.
Because of the firewall, I recommended that with the local IP. Is something like ufw installed?
Yes is. Habs checked… UFW is apparently pre-installed.
Here is my working bungee cord config: https://hastebin.com/...a.makefile
Here is my lobby config:
Do ufw disable and try if everything works. If so then do ufw enable and
ufw allow from localhost to any port 25565 proto tcp
For all your Minecraft ports.
OK. Thank you.
I think I'll definitely have to fall back on that, but the problem is probably more with UFW…
Did it work out?
So this is weird, the one with a firewall works a 1.15 server… But my 1.8.8 Spigot server doesn't. Same problem. Bungeecord works too.
Well then try 1.8.9 do you have different configs?
Unfortunately 1.8.8 is the newest version of Spigot, the 1.8
Give PaperMC a try it is actually better in terms of security anyway. You can also use newer Minecraft versions and then work with ViaVersion.

Oh one thing comes to mind did you set bungeecord to true in the spigot.yml?
Okay, then thanks for the help, I think I can do it alone.
The Bungeecord network here by me is older and has been on new (Linux) servers several times.
Yes bungeecord is true…
You're welcome. If you need help with something at some point, please feel free to contact me.
