TL;DR: Help me fix this error so I can run my own server!
I have created a server on my PC. When my friend connects over the internet, he gets kicked after about 10 seconds with that error. He then made the server, and when I connected to him I had the same issue. On the server side, it just says the user timed out.
We are both running 1.14 fresh installs
We are both running JRE 1.8.0_221.
We have both forwarded port 25565 correctly(which is why we are able to connect at all).
All of the Java Platform SE Binary have been allowed through firewall.
I tried on my laptop as well, which works over LAN, but when I connect with a VPN I get the same error.
Both of us have Telstra routers if that could effect it.
