Storefront to connector comms fails if the server certificate on the connector is replaced.

In the system event logs we can see event id 15021.

When we review the service monitor on Netscaler to verify https communication with the connector we can see the status is down.

The customer has configured HTTPS communication with the connector as per:

Binding is no longer valid as it refers to a cert that no longer exists on the Connector

Queried broker specific appids on connector:

Get-WmiObject -Class Win32_Product | Select-String -Pattern "broker"

Removed binding:

Netsh http delete sslcert [ipport=]IP Address:port

Ref: https://learn.microsoft.com/en-us/windows/win32/http/delete-sslcert

Added binding back using known Appid from Get-WMIObject command above:

netsh http add sslcert ipport=<IP address>:<Port number> certhash=<Certificate thumbprint> appid={Any GUID}

After updating the Server certificate on a connector, Storefront is no longer able to reach the connector over HTTPS
