Hello,

Thank you for your post.

You should be able to monitor your certificate by using the SSL Certificate Sensor.

Is the device reachable from the probe running the sensor? Do you perhaps have a firewall that may block the connection? Have you tried entering the address to which the certificate is issued to into the "Virtual SNI" field in the sensor settings?
