CloudLinux reports JWT token is expired

Symptoms

Sometimes, you will get a notification from CloudLinux about your JWT token being missing or expired, similar to this:

CONFIG_TEXT: Check existing JWT token:
FAILED: JWT token expired. Please check for JWT token in path "/etc/sysconfig/rhn/jwt.token". Try running "rhn_check" for getting a new token if it is absent. Server can't collect and send statistics to Centralized Monitoring if you don't have a correct JWT token. Link to FAQ and troubleshooting https://docs.cloudlinux.com/cloudlinux-os-plus/#faq-2. Please write to support https://cloudlinux.zendesk.com/ if you can't resolve the issue.
Command for disabling this cron checker: "cldiag --disable-cron-checkers check-jwt-token"

Cause 

This can happen when the token set up by CloudLinux has expired and hasn't been updated yet. You can generally remove the token and regenerate it. 

Resolution

1. Access the server's command line as the 'root' user via SSH or Terminal in WHM.

2. Move the jwt.token out of the way.

   # mv -v /etc/sysconfig/rhn/jwt.token{,.$(date +%s)}

3. Ensure CloudLinux is registered.

   # clnreg_ks --force

4. Generate another token with the rhn_check command.

   # rhn_check

5. Verify that the token has been recreated.

   # cat /etc/sysconfig/rhn/jwt.token
