Each time I join any server I get this error saying "Internal Exception: Java.io.ioexception: An existing connection was forcibly closed by the remote host". I spent about 4 hours researching and troubleshooting this problem and thought I fixed it late last night. Then I come to log in today and I get that error message in less than a minute of joining. I have tried resetting my router, restarting my PC, re downloading Minecraft, turning off my firewall and antivirus, starting Minecraft from the old launcher, updating Java, and creating port forwarding yet none of this has worked.

When I thought it work I turned off my firewall and antivirus and it worked. Yet when I logged in today I had those same settings and it wouldn't even work for a minute. This may be an internet issue instead of a Minecraft error, but the only other interesting thing that has been happening was that about 30 minutes before posting this I was losing connection to my Rocket League games while earlier in the day it was working perfectly.

I would much appreciate a fix for this problem, but i understand if it is a WiFi problem that you guys might not be able to help my out. Thanks.
