Unity Multiplayer: when i hit another player all players health bars go down

i am using OnTriggerEnter colliders to register hits with a sword, when the sword collider hits a collider with the tag player it reduces the health bar. the problem is that when i hit another player both the health bars go down, im pretty sure that this is happening because all players have the same tag as i need it to work for multiplayer but i dont know how to fix it

here is my code:

 private void OnTriggerEnter(Collider other)
 {
         if (enter)
         {
             
                 if (other.gameObject.tag == "Player")
                 {
                     healthbar.value -= 20;
                     
                 }
                                                      
         }
 }

Thank you for your time

p.s this is also my first game
