Broker Certificate Renewal

The Broker certificate must be renewed before its expiration to maintain communication between Remote Control components. This process involves renewing the certificate keystore, uploading the new certificate, and ensuring all Brokers and Targets are updated accordingly.

The Broker certificates can reach their expiration date in one year or more. You can check the expiration date in the All Trusted Certificates page on the Remote Control server by selecting a specific certificate in the list.

It is suggested to renew the Broker certificate before the expiration date to avoid broken communications between Remote Control components. Following is the list of suggested steps:
  1. Renew the expiring Broker certificate keystore.
  2. Upload the new certificate to the Remote Control server (PEM format).
  3. In case of CA signed certificate, upload the CA chain certificates to the server if they have been changed (PEM format).
  4. The new certificates will be automatically downloaded by the Brokers and the Target on next callHome or next service restart.

When the Target can’t directly reach the Remote Control server and the Remote Control server and/or the Target have a version 10.1.0.3xx or earlier you need to manually upload the new certificate using the Remote Control Target Wizard (refer to Creating Remote Control target configuration tasks). You can copy the broker.certs file content from one of the Brokers with the updated list and paste it to the Trusted certificates for Broker connections box. Note that the whole content of the broker.certs file on the Target machine will be replace with the provided list of certificates.

Once that the new certificates have been updated on all Brokers and Targets you can copy the new certificate keystore file to the Broker machine (check the supported formats from the Remote Control Broker Certificate topic) and reconfigure the Broker to use the new keystore.

Once that the Broker service has been restarted you can follow the instructions from the Remote Control Broker Certificate topic to perform the certificate validation.

Once the validation is completed you can safely delete the expiring/expired certificate from the All Trusted Certificates page on the Remote Control server.
