Device certificate Issuer and other information not updating on the browser's certificate details

We recently updated a device certificate on an F5 device but we encounted lost access on the GUI after the device cert application. We stumble upon this article https://support.f5.com/csp/article/K52...

    Hi guys, this has been fixed. internal CA provided a faulty certificate. Fixed after getting new cert. Thanks!

I have not used the method in the link that you provided but I have used the process in the following link starting at section "Replace the BIG-IP system self-signed device certificate" which should produce the correct results for you. Please make sure to backup your two files that you are replacing before you replace them.

    Hi thanks for your reply. Will this work with a cert given by an internal CA? not 3rd Party CA.

      This will work with any CA as long as the cert and key match. You will still receive the warning in your browser when you attempt to connect but if you import the internal CA cert it will no longer receive that error assuming you connect using the CN in the SSL cert.
