No interactions between 2 players in Dark-Multiplayer

[Maxz752]

KSP version: 1.7.1.2539 - Windows x64

The problem: When I and another player enter a dark multiplayer server, we can't interact with each other, for example: we can't see the physical shapes of the ships, If someone's base was damaged, the other one can't see it.

Installed mod: Dark Multiplayer v0.3.3.0

Reproduction steps: Download the D-MP "Client" version, then install it by placing the folder named: GameData(this folder you will find in the downloaded zip file) into the "Kerbal Space Program" file. Also you should install the D-MP "server" version, make sure the port forwarding was successful. After the installations, open the server, let 2 players enter and, as one of the players, you may not see the player, his ships, or any damage he made to the base.

Note: I had an internal IP, and the other player had an external.

 

 

 

 

 I will appreciate any help, thank you.
