Forge Server Disconnecting Me

[Aidan5750]

I recently made a forge server to play on with a few friends. At first, I attempted to run the server on my computer as I was playing. I was unable to join the server using my ipv4, public ip, and "localhost", so I got a small computer to host the server. Now, every time I attempt to join the server it kicks me after a few seconds. this is the exact thing the server has said every time:
