Minecraft Forge doesn't responding when entering a server

[Short]

I am playing in version 1.15.2, with my own modpack. It works perfectly in singleplayer and has no conflict, but when I try to enter a server that has the same mods (with the exception of clients), the game is only in "Encrypting" and ends up crashing and not responding for a few minutes; when he comes back, it appears on my screen: "Desconnected". I've tried Lan server, server created by folder (using the prompt), and a own server (purchased), but this always happens. I don't know if the problem is really the forge, I don't really understand it, maybe it's something else, but it costs me nothing to ask!

Not exactly. I had tried to enter, after no success, I started in vanilla and joined another server.

Dude, I don't remember. I tried to enter the modded server, but it didn't work. After that, I uninstalled minecraft and entered the hipixel.
