so I have been trying EVERYTHING for it to work. my friends have an amazing time with no problems on my realm but i crash everytime i join. sometimes it works but rarely. i've tried turning off firewall i've tried updating my computer messing with what my firewall accepts but everything seems good. i've even uninstalled minecraft completely even re installing java. when i crash the message has java included in it but i've even updated my java. the error message is

internal exception: java.io.IOException: An existing connection was forcibly closed by the remote host
