blueprints are not working on a dedicated server

Hi, so basically when testing on single player, all blueprints and everything worked fine, but when i created a dedicated server and tried to test on it, the blueprints stopped working, i couldnt do anything but walk, i couldnt even run when i try to run the game starts to glitch and i stay slow, i really could use some help iam working on a big game and i’ve seen people have this problem back from 2016. Thanks.
