Getting kicked from my server

so im playing a modded smp with friends and every time i join i stay for about 3 seconds before getting kicked and it saying "connection lost" and i have no clue how to fix it, my pc is strong enough to handle it and its not my wifi

saw this on another post but it might help: https://mclo.gs/gB76CNH

anything?

Please provide the full and exact error message that is displayed

all it says is connection lost and a button that says back to server list, it lets me join for about 3-6 seconds before that, that's all the information i have

I'll do that now! Thank you

so apparently the mods list and mods i have downloaded are the exact same, and it still refuses to load and still kicks me instantly, the only thing i can think of is me having a different version on each one but apparently its the exact same so i have no clue anymore
