  • Hello,

    Please execute the following command on Ubuntu to check if the service is ready to listen on port 3731. If the output of command is null, please start the service first.

    netstat -na | grep 3731

    Besides, is there an Azure NSG associated with the subnet in which the Ubuntu is deployed. If so, please also create a rule to allow inbound traffic to port 3731.

    Finally, just in case, please stop the firewall on Ubuntu using the command below.

    sudo ufw disable
