Hello,
Could you be a bit more clear? Do your relays sync with just IOG relays in the topology? With the cardano-node on relay running, can you see that the port is open using this tool?
If the ports are not open properly, the nodes can typically make outbound connections but not receive inbound connections.
Port Checker tool (only to check relays as block producer should be locked down to only talk to your relays):

Once this has been completed, you will want to double check your topologies as well as the command to start the nodes, particularly the --host-addr param
