Internal Exception: io.netty.handler.timeout.ReadTimeoutException

What i expected to happen: Minecraft loads as normal and lets me join servers.
Reality: 95% of the time not being able to join. Kicked of servers around once every 30 minutes, if I did manage to get on in the first place, anyway I am being kicked for this error message:

Failed to connect to the server
Internal Exception: io.netty.handler.timeout.ReadTimeoutException.

To reproduce: Try to join a minecraft server...

long story short, this error wasn't a duplicate of MC-34646 and was not fixed...
