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.

Command for disabling this cron checker: "cldiag --disable-cron-checkers check-jwt-token"

Environment

• CloudLinux OS Legacy (Not Shared PRO)
  

Solution

In the CloudLinux OS Legacy edition, the JWT token issue can be ignored.

Check if there is a valid CloudLinux OS Shared Pro license:

# /opt/alt/python37/bin/python3 -c "from clcommon.lib.jwt_token import jwt_token_check; print(jwt_token_check())"
# cldiag --check-jwt-token

• If the result is negative, disable the cron checker with the following command:
  cldiag --disable-cron-checkers check-jwt-token
• If the result is positive, run the following command to update the license status:
  

  rhn_check

Cause

The cldiag utility checks server for the valid JWT token required for the X-Ray. With no CloudLinux OS Shared Pro license, one may experience this error message.
