Some players cannot join my server; I will refer to them as timeout players
As mentioned, I am hosting a Paper with the default configuration and a few plugins. Many players can join the server normally, including me, but some cannot join the server without a timeout after a few seconds. At first these timeout players connect to the server and successfully send packets to the server in real time, which allows other players to see the timeout players' inputs in real time, but the timeout players receive the packets very slowly and very late, which causes them to get a timeout kick after several seconds. It can't really be their fault, as they can connect to other servers without any problems and have tried it with several launchers, and it still doesn't work.
This paper server is connected to a VPS that acts as a proxy because the paper server is behind a NAT. But it can't really because of this because it works with a vanilla server without any problems and the timeout players receive packets in real time without any Problems there.
What is the problem? What can I do?
