I keep getting kicked from Hypixel servers.

[bigpoolofthor]

I am playing Hypixel as normal and anytime that I switch to different lobbies there's a good chance that I either get sent to the Hypixel Prototype lobby, or just get booted back to the server list. I am running 1.8.9 using opitfine, Not Enough Updates, SkyBlock addons, and Skytils. All of them are on their stable latest release version. How do I fix this.
