You notice that the self-signed certificate for port 41002 communication on the Symantec Messaging Gateway (SMG) expired.
The port 41002 is only used for the bi-direction communication between the Control Center and the scanner.
10.7.X 10.8.X
The self signed certificate is initially generated for a period of two years from the date of update or installation.
There is no possibility to implement a CA signed certificate or manually renew the existing certificate for the communication between the Control Center and the Scanner on port 41002. To mitigate the issue, update the current version of SMG. This update will trigger the generation of a new certificate.
