Where can I find documentation on indestructible actors?

First time posting a question, apologies if I have done anything wrong in the question posting.

My problem is when I try to destroy actors as part of a multiplayer game, using a raycast to hit a health variable down to zero and triggering the destroy method, the actors’ do not get destroyed. I read that the destroy method returns true or false on the unreal documentation and by passing it through an if statement I found that it was returning false and thus indestructible.

When I looked up about why it was returning false I could only find one forum post where the person had not properly called Super on begin play, but I checked and I had. I could not find further information and was hoping someone might have a link some form of information on indestructible actors.

Thanks

My first thought is if the call to Destroy has Authority?
