Internal Exception: java.net.SocketException: Connection Reset MESSAGE

Every time I join any multiplayer server, whether it be a public server or a realm, the gameplay (besides my avatar) does not move for several seconds until I become disconnected with the following message: Internal Exception: java.net.SocketException: Connection Reset.

Sometimes my character is spawned falling down the void until I disconnect. Sometimes my character is stuck underground in a block until I disconnect.

I have tried multiple tutorials, both on Google and Youtube, to fix this problem... none were successful. I even tried uninstalling and reinstalling Minecraft various times with nothing changing. I also tried joining these multiplayer servers on another, much more new, computer. Nothing changed. I have spent days trying to fix this issue, and I am starting to think that this problem is not from me but from the game itself.

 

I hope this is fixed soon, considering how I just sent more money for the realm's monthly subscription and I cannot even play on it.
