Your nodes will stay in sync as they can make outbound connections, but they cannot process inbound transactions if the relay port(s) are closed to inbound traffic. Check your relays using this tool to ensure your relay ports are open (make sure the nodes are indeed running): > **[Open Port Check Tool - Test Port Forwarding on Your Router](https://www.yougetsignal.com/tools/open-ports/)** > > Port checker is a utility used to identify your external IP address and detect open ports on your connection.

Can you confirm whether or not the relay ports are open to inbound connections?
