The checkallsslcerts Script

Valid for versions 118 through the latest version





Last modified: November 1, 2023



We strongly recommend that you only run this script if cPanel Technical Support advises you to do so.

The system runs the /usr/local/cpanel/bin/checkallsslcerts script in the following situations:

  • During the nightly cPanel & WHM update (upcp) process.
  • When you purchase or add a cPanel & WHM license.

This script performs the following actions:

  • Requests a SSL certificate to replace certificates that meet any of the following conditions:
    • It maintains a weak signature algorithm.
    • It has been revoked.
    • It does not have a Subject Alternative Name (SAN) extension.
    • It does not have an Extended Key Usage (EKU) extension with the Server Authentication value.
    • It is self-signed.
    • It is invalid (for example, your server’s hostname must be valid and resolve in DNS).
    • It will expire soon.
  • Updates the SSL certificate for all cPanel & WHM services.

Run the script


We strongly recommend that you only manually run this script if cPanel Technical Support advises you to do so.

To run this script on the command line, use the following format:

/usr/local/cpanel/bin/checkallsslcerts [options]


Use the following options with this script:

--allow-retry If the cPanel Store continues to process the hostname certificate request, then the system checks the cPanel Store again in an hour. For more information about this option, see the allow-retry options section below. --allow-retry
--verbose Run the script in verbose mode. --verbose

The allow-retry options

When the system checks the cPanel Store after an hour, it runs the following command:

/usr/local/cpanel/scripts/try-later --action '/usr/local/cpanel/bin/checkallsslcerts --no-retry' --check '/bin/sh -c exit 1' –delay 60 --max-retries 1 --skip-first

If the system must retry the SSL certificate update process, it adds an entry in the at daemon (atd) job queue. To view, execute, or remove a job from the atd queue, use the /usr/local/cpanel/scripts/try-later script with one of the following options:

Option Description
atq List all at queue jobs.
at -c # Display the contents of a specific job.
at -c # | sh Manually execute a queued job.
atrm # Manually remove a queued job.


If this script detects errors when it runs, it sends an email to the system administrator that contains warnings about those errors.

Disable an automatic hostname certificate

To disable an automatic hostname certificate’s installation, run the following command:

touch /var/cpanel/ssl/disable_auto_hostname_certificate

To disable the automatic replacement of all expired service certificates and disable notifications about expired or expiring service certificates, run the following command:

touch /var/cpanel/ssl/disable_service_certificate_management
