Vanilla Forge - My Personal Server kicks me

Thanks in advance to whoever helps me with my problem

Here's the stuff: I always hosted vanilla minecraft servers, which worked fine from my laptop for aproximately 10 people. I'm attempting to enter the realm of Forge, and tried to host a pure vanilla Forge (no mods loaded); whenever I do, I can enter the server, play for between 1 and 3 minutes, and then get kicked due to an error:

[17:57:15] [Netty Server IO #2/ERROR] [FML]: NetworkDispatcher exception java.io.IOException: An existing connection was forcibly closed by the remote host

I am using the Forge Server version 14.23.5.2838, for Minecraft 1.12.2

Any type of help is apprecieated. Thanks!

EDIT: I can host Vanilla Minecraft servers fine, tried 1.12.2 and 1.14.3
