Unable to remotely enroll machine

[bbot]

A machine lost connection to our JSS and I'm trying to re-enroll it. I've been able to re-enroll machines remotely that are on VPN with no issues in the past.

The machine:
- Was last enrolled over a month ago
- Resides where the time zone is 2 hours ahead

I've tried:
-remove framework
-install using Recon 9.97 (failed)
-ssh'd in and run sudo jamf enroll -prompt (failed)
-It fails checkJSSConnection

The error:
"Recon failed during the submit process..
Downlading CA Certificates... There was an error

Error enrolling computer: Unable to establish trust with the JSS - Connection failure. "The operation couldn't be completed. error 502"

Are you on Linux by any chance? I just had the same problem, and it was because the certs were not copied over during the 9.97 upgrade.

Also tried copying the quickadd package and installing locally on the machine. Removed jamfframework, then tried to isntall using installer -pkg xxxxxxxx.pkg -target /

Received an "upgrade failed (installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.)
