 Automating RQSTR Channel Restart After Vendor Security Refresh

Hi,
 
My MQ server (QMINE) is behind a NAT, so it is not directly reachable from the network. However, my vendor’s MQ server (QVENDOR) is publicly accessible, allowing me to connect from QMINE → QVENDOR without issues.
 
Since traffic needs to flow in both directions, I have configured a Requester (RQSTR) channel on my side and a Server (SVR) channel on QVENDOR. The default Sender/Receiver (SDR/RCVR) channel setup would not work because QMINE has no public IP and is not reachable externally.
 
Issue:
QVENDOR shares its MQ server with other systems and occasionally updates its certificates. When they do this, they run REFRESH SECURITY, which disrupts the connection. Afterward, I have to manually stop and restart the RQSTR channel for it to reconnect.
 
Question:
Is there a way to automate this process so I don’t have to manually restart the RQSTR channel each time QVENDOR refreshes its security settings?
 
Thanks!
Pete
