Networking - spawn actor from actor at client (character -> weapon -> projectile)

I cant get it how to spawn projectile from weapon BP for client in multiplayer… Server works but when client spawning projectiles, server or other clients does not see them.
My setup is:

  1. spawn weapon and attach in character bp

  2. in character input action fire → weapon reference → fire function in weapon

i tried run on server, multicasts etc… but cant get working it…

could someone help me please?
