The application web logs shows below error:

See the InnerException for details. ---> Could not subscribe to SnowSoftware.LicenseManager.Web (See inner exception for details.)

Looking at the event view log we can see below error:

Unable to update the IP address on Isatap interface isatap.{3431ABF3-5EF2-47B1-8C45-ECB74BBC6B89}. Update Type: 1. Error Code: 0x490.

Which indicates that a network issue has occurred on the server and all the services are now stopped.

In this instance we restarted the NATS service.

We then made sure to restart all of the Snow services.
