    We want to activate HTTP/2 on our server but before we proceed, we want to make sure there is no issue with our setup.

    Here's some background information:
    1. All our websites use Fast-CGI (not mod_php or php_fpm)
    2. We have a Roundcube installation beside ISPConfig and I don't know what interface it's actually using, to be honest. I would have to check with our team if necessary.
    3. Most of the websites we're hosting are secured with Let's Encrypt
    4. We use Apache
    5. We use the latest version of ISPConfig (3.2.5)

    Is there any precautions to take before proceeding? Is ISPConfig fully compatible with HTTP/2 ?

    Thanks in advance :)

    You can safely enable it. For Debian 10, run
    a2enmod http2
    a2enconf php7.3-fpm
    systemctl reload apache2
    a2dismod php7.3
    systemctl restart apache2
    a2dismod mpm_prefork
    a2enmod mpm_event
    systemctl restart apache2
    till, ahrasis and invino like this.
