Now, I've been having this problem for a while, but whenever I join a server, it goes well for a while, until I randomly crash. I've seen multiple reasons for the crashing, here's the log for one of them:

Another problem says that there is a Network Dispatcher Exception,
P.S. I'm only running Optifine 1.9.0 and Forge 1.9.0. I play on a Vanilla server, namely, Hypixel and Mineplex, it doesn't crash on Cubecraft though, is it Hypixel's/Mineplex's problem? How do I fix it? Once I remove the mods it doesn't crash, however, if I download Optifine on its own (Using an Installer) it says that it's missing forge components. How do i fix this? Help.
Thank you in advance. <3
