SSL Cert sensor not updating after renewing cert



I updated a cert on a server, and deleted the old cert, however the ssl sensor for that server still shows expired as though it is pulling the old cert. How do I update the sensor. I already tried deleting and recreating the sensor.

Hello Hmboyer,

Thanks for reaching out to us! Is there some kind of load balancer in front of the web site in which you need to replace the certificate as well? Or are there different web pages monitored on the host and is the wrong SNI entered?

You can download the certificate by entering the sensor settings to write the results to disk.

Kind regards,
Felix Saure, Technical Support Team
