Cant connect to the server or getting kicked as soon as i join the server

i'm trying to set up a moded server to play with my friends, at this point a have some mods on it but want to try them on the server, i've the same mods i've installed both on my server and on my client and they run completely fine on singleplayer.

When i try to join the server there 2 outcomes, the 1 one is i get imediately kikcked when joining the server and get the error message "a conection was forced to stop by a remote host".

Example 1 (i'm from brazil thats why the error is partially on brazilian portuguese):

the second outcome is that i'm possible to join the server, but as soon as i enter anything is loaded and i get kicked or some chunks get loaded but i cant interact with anything and get kicked after some seconds.

Example 2:

i've already tried to change my dns. turn my moden off and back on and i have my windows firewall down.

I now Installed the random patches mod, and now i can join the server, but everything is slowed down.

When i write a message in the minecraft chat and send it, id dont appears, but i can see it instantly appearing in the console of the server. if i break a block it takes some minutes to actually break and drop. After some more minutes i get kicked out again

Do you still get kicked with the same error message? If yes, make sure that the EXACT same mods installed on both your PC and the server. It is not enough to simply have the same mods installed, they must also be installed in the exact same version. Likewise, the version of the mod loader (Fabric/Forge) must be identical.

I went through all mods one by one checking their versions and all were the same.

So today, i tried joining the server again and everything was right, it joined quick and everything was normal.

I didnt change anything since yesterday.

if it starts doing that again ill post here some more help lol
