Azure Sphere Device Communication Service Crash issue RRS feed

  • Question

  • The Azure Sphere communication service keeps crashing every minute. I did change the service logon to "Local"  but doesn't seem to resolve the issue. Here is the error captured in the event viewer log. Any fix for this?
