One of your mods has a broken network packet, make sure all of them are up to date.

Please add -Dforge.logging.mojang.level=debug to the JVM arguments of your Launcher.
Launch the game and produce the error, then post debug.log from the logs folder.
Vanilla Launcher: Launcher -> Installations -> Edit the Forge Profile you are using -> More Options -> Add the Argument to the JVM Arguments.
