[client] issue with multiple ip addresses

Hello,

joining a server is not possible when client has multiple ip addresses on network interface card.

in my case:

Ethernet-Adapter 1G:

   Connection-specific DNS suffix  . :
   Description . . . . . . . . . . . : <censored>
   Physical Address  . . . . . . . . : <censored>
   DHCP active   . . . . . . . . . . : no
   Auto configuration aktive   . . . : yes
   IPv6 Address. . . . . . . . . . . : <censored>
   Local connection IPv6-Address . . : <censored>
   IPv4 Address  . . . . . . . . . . : 10.0.0.1
   Subnet mask   . . . . . . . . . . : 255.255.255.0
   IPv4 Address  . . . . . . . . . . : 192.168.2.66
   Subnet mask   . . . . . . . . . . : 255.255.255.0
   default gateway . . . . . . . . . : fe80::1%7
                                       192.168.2.1
   DHCPv6-IAID . . . . . . . . . . . : <censored>
   DHCPv6-Client-DUID. . . . . . . . : <censored>
   DNS-Server  . . . . . . . . . . . : fe80::1%7
                                       <censored>
                                       <censored>
   NetBIOS over TCP/IP . . . . . . . : active

the 192.168.2.xx is for internet access and the 10.0.0.xx is for UniFi management

only one default gateway is set (192.168.2.1)

The client tries to join a server and got disconnected with the message "The server host has left the game"
