Try to connect with only forge and no mods installed?
If it still throws that error then I have no clue what's up.

Allons-y!
Alright turns out it's Optifine for some reason. With Schematica loaded but Optifine not I managed to connect. Also with just Optifine and Forge I couldn't connect, but just Optifine I can. Weird
