Client cant posses a pawn or spawn with player start when they join game

I’m testing multiplayer in my game but in a fully packaged game no matter what player I use the client never posses as an actor I’ve tried even doing it through blueprint and player start but it just won’t work I can’t figure out why the client cant spawn.
so what should I do to fix this

run your packaged game with the ‘-log’ switch and see if you can read any good warning/error message

I found out the client is posing pawn but then he will just be loading forever and he will never be able to se him self or other actors it seams to be the only character that will load is the third person character

Possess function is server sided maybe you should call it with a Replicated Execute OnServer kind of CustomEvent.
