Bug Description

I get disconnected from the server over a random interval of time between 2.5 mins to 20 mins. Sometimes I can stay on for several hours, sometimes I can barely stay on. I've tried every fix that pops up in google and none of them work. I'm the only one who seems to have this issue, no one else. I'm getting really frustrated because I've tried basically everything that shows up in google.

Did this behavior use to work in the previous version?

List of solutions:
I've tried disabling my firewall on ethernet and on wireless connection.
I've reinstalled the lastest version of java 1.8 3 times
I've tried running "netsh winsock reset" and netsh interface ipv4 set subinterface "local area connection" mtu=750 store=persistent" in the command prompt
I've downloaded the config folder from the server and replaced my files with those
