Everytime i join our Beammp server my friend gets kicked

So before i join the server my friend can join and play on the server and then when i join the server my friend just gets disconnected for no reason

I use hamachi and we connect to a network with it
everything runs fine until i join the server then i can only play on it and nobody else can play like when i join first my friend can join but for like 30 seconds and then he get disconnected for no reason

Im the host of the server and my internet runs perfekt with no distruptions
