Internal server error + My forge server ignores mods

[lostfresh]

So i have server on 1.16.5 forge. Ive got all mods in the mods folter and all other important files. The server still runs without the mods.¨What should I do ? 
Also when we try to play with my friend on hamachi, he kept getting kicked for internal server error. We got same forge, mods.

Im using the bat file to run "server.jar" which is minecraft 1.16.5 server. The forgeserver.jar file was made by the forge server installer but cant use it to start server. The server still runs on forge. I can join only with the forge. But I dont know why is it ignoring my mods.

Please if you guys know how to fix internal server error or this weird server thing ignoring my mods. Thanks yall

(yeah i dont know if i was supposed to put all the modpack files there but probably yes lol)






Edit: So I just found out that im really dumb and the server is really working on the 1.16.5 vanilla. HOW am i supposed to change it when the forgeserver.jar doesnt do anything ?
Edit number 515: so i somehow managed to make the server start. ill make feedback
Edit : 3 so my portfowarding doesnt work smh . Now we are just struggling with the internal server error. BRO how it can be so annoying and everything, im literally doing this for like 8 hours in total

Don't rename the files created by the Forge installer.

It's not recommended to put the server in .minecraft.
