AI not attacking Replicated Client?

I have an Blackboard/BehaviorTree AI that I really want to follow and attack Nearest player Insight.
My players is the ThirdpersonCharacter Class. I have two PlayerStartPoints and everything in that area is fine.

My AI only attacks Host and totally ignores the Client. I have set every possible thing to Replication on the AI.
I can’t do any “Switch has Authority” on the “ChasePlayer” Task. (Bcus it’s from a Blackboard???)

Been stuck forever with this and no one seems to wanna help me. And I try not to give the project up bcus I have put so much time into it.

If you want screenshots from my blueprint I can fix it.

Can someone help me?

AI are run only on the Server. Then the Server tells all the players what it sees, AI Attacks should be set to run on Server.
