JSS Won't Push out Configuration Profiles or Apps

[latanyamonique]

We are having an issue with our JSS pushing out apps and profiles to five out of our 100 devices. I have checked the certificate and verified communication with the JSS from other devices. Any hints?

Anything in the /var/log/jamf logs?

Is the time/date correct on the clients where it isn't working?

What version of JSS? Current versions of the JSS require that it be able to reach out to the 17.0.0.0/8 (Apple's Network) netblock on port 80 in order for push notifications and the like to work.
