i have an openvpn server which was working perfectly until a few days ago. it just suddenly stopped working. i can connect without any error but there is no data going through. i kept on changing ports and checking all the configurations from server.conf to ip routing and UFW but nothing worked and still the same problem. until i was checking the log file real-time while connecting to the server and i found out something strange. the port on the connection from my ip to the server is different as the port i assigned in the server.conf and the client conf file. is this normal or something strange is going on here?

int his log shows im connected via port 15317 but the port in the server.conf and the client config file is 43729.
funny is that port 15317 is not even open in UFW.
