**I have rent an Ionos VPS Server an want to run a Beammp server on it.
My problem ist, ihave opened the Port: 30814 UDP and TCP
But i get the message from the server Console:** Error during handling of code C - client left in invalid state, closing socket: bad address cast
My ionos server has only IPv4 an i get this message too: Failed to unset IP_V6ONLY on UDP, only IPv6 will work: Protocol not available
What can i do? i cant connect on my Server
