I have a problem like 3 months ago and I cant play multiplayer because when I enter to any server just appear me this message Internal Exception: Java.io.IOException: An existing connection was forcibly closed by the remote host. every moment i play. i cant even play 10 minutes before this happens and also I reinstalled minecraft 2 times if there is any problem but still happening. (I dont have any mods, any texturepacks, nothing, just playing 1.12.2) and I deleted java and reinstalled again. nothing...

(Also I move to another country and my internet is better than before, I dont think is my internet connection because i played in different places and still happen). Please help me
