I will check from the command level :
ping tools.cisco.com
smartlicense status
try register force :
smartlicense register force
What version did you upgrade to?
Check, do you have valid License keys :
licensekeys (Verify your feature keys are still valid)

Hello, upgrade to version: Version: 15.0.5-016. The problem is that the service is probably not running on the gateways at all.
The Critical message is:
Connection to URL Retrospective registration service failed. Certificate verification failed. Contact Cisco TAC for assistance.
