The JumpCloud agent will start, but no changes are synchronized. The JumpCloud log indicates:
Get https://agent.jumpcloud.com:443/policyconf: x509: certificate signed by unknown authority
As of agent version 0.9.620, a new certificate was issued for agent communication back to JumpCloud. Older agents that were not updated will still use the old certificate which is no longer recognized.
Reinstalling the JumpCloud agent will upgrade the existing agent to the newest version. Uninstallation will not normally be necessary. The version can be checked in:
MAC | LINUX: /opt/jc/version.txt
WINDOWS: C:\Program Files\JumpCloud\Plugins\Contrib\version.txt
If uninstalling is needed to facilitate a functional installation, a new system record will be created and the old one orphaned. Any group memberships or users bound to the system will need to be reassociated.
