RPC(Run on client) Called from server, never fires on client

Hello. I have player controller, after begin play and switch authority, server call an RPC to client and this RPC never fires.

If i am changing replication to multicast, than RPC fires on server but not on client.

I found what, if im doesnt switching authority to client, when call RPC it fires. Screen relaited.

Ok, the problems is what Client and server blueprints is emmm… as i understand, need some time to establised connection after construction, for RPC calls.

So i set small delay at its fine.
