    The problem was resolved. The firewall did not allow the local repo to access the rhui4-1.microsoft.com domain.

    Thanks!

    @Buck Soong Tan

    The issue you’re encountering is related to SSL connection errors with Red Hat Update Infrastructure (RHUI) on Azure Linux VMs. Here’s a summary of the troubleshooting steps:

    • Expired RHUI Certificate: If the RHUI client certificate is expired, you’ll need to update the RHUI package to renew the certificate. Use the following command:
    sudo yum update -y --disablerepo='*' --enablerepo='*microsoft*'
    • Missing RHUI Certificate: If the RHUI certificate is missing from the /etc/pki/rhui/product/ directory, you’ll need to reinstall the RHUI package that contains the certificate.

    For detailed instructions and more troubleshooting steps, you can refer to the Microsoft Learn article on Troubleshooting common certificate issues in RHUI. This guide will provide you with the necessary steps to resolve the SSL connection errors you’re experiencing.

    Hope this helps! Let me know if you are still having issues and I can further assist.
