Cant synchronize hitbox

Hello, I'm making a 1v1 2d fighting game and I cant quite get the meele hitbox right.

both player connect, spawn the player prefab and have synchronized movement and animation. However the meele hitboxes do not work.

My plan:

1)In the player prefab, make a child gameobject called MeeleHitbox with collider2D

(isTrigger true) and give it a tag called Meele Hitbox.

2)Give the player prefab onTriggerEnter2D and look for collider with the tag.

3)Active and Inactive based on user input.

Problems:

1) Players ignore each other Hitboxes.

it has something to do with it being a child object/photon instantiated because I tried adding the same gameObject to the scene and the Trigger was called.

2)I can't get them to synchronize.

For testing, I tried the following code to make them Inactive:

The log I used just before the ReceiveNext was called only twice at the beginning and

Hitboxes got inactive only in one screen:(they are the white squares)

The hitboxes have both photon view and photon transform view classic.

please help.
