    Hello,
    I'm unable to access the ISPConfig control panel at isp.xxx.xx:8080 due to an SSL certificate issue. How to update the SSL certificate for the ISPConfig panel?
    Message: "The certificate is not trusted because it is self-signed."
    Any advice?

    regards

    First, you should still be able to access ISPConfig by accepting the certificate in your browser.

    To get a valid Let's Encrypt certificate, ensure that the hostname of your server is correct and exists in DNS, and it must be reachable on port 80. Then run:

    ispconfig_update.sh --force

    Choose to reconfigure services during update, and choose that the updater creates a new certificate.

    Hi, thanks for the quick response.
    Strange that there is no "accept the certificate" in the browser ... actually in my FF-developer version(and Chrome). Just tried it again - after your suggestion - with normal FF and I could "accept ...", so I do have access to the panel now :)

    I do not have root access to run 'ispconfig_update.sh --force'.
    Is there another way to achieve this?
    Or, the person who installed ispconfig on the server isn't available anymore. How to get the credentials anyway?

    thanks!

    No. This is part of the base system setup and only accessible to the root user.

    So you are the new admin but do not have root access? This question is not ISPConfig specific, as it is about the underlying Linux system. I suppose the only option is to boot the server into a rescue system and then set a new root password using that system.
