Description: 

A configured certificate could not be loaded from store. The serial number is attached for reference.

Here’s what the flow of events in the logs look like:

Solution

The reason why the Edge services are not able to start is because the certificate the interfaces (public and internal) have expired.

Notice that one of the events logged actually specifies the serial number of the certificate.

To correct the problem, simply renew or replace the expired certificates with valid ones, assign them to the Edge server’s interfaces and restart the Edge services.
