MultiPHP Timeout when changing configuration or Php version

[dantahoua]

I finally wrote here after hours of testing and research...

When I change the Php Version for a domain in MultiPhp (Whm), it takes ages (sometimes up to 2min) before the website is not timed-out!
Same thing if I change the configuration of Php-FPM for a domain or just enabling/disabling Php-FPM for a domain.
After a while the website is up but sometimes, randomly, the website takes 5sec to 10sec to start to load.
Where can I start looking, which log?

I have 66 websites on the server, but not that much traffic on those website. Every website has is made with Wordpress, I use cache. Every website load very fast 9 times out of 10!
I'm sure it's a little bug or misconfiguration hidden somewhere, the BIG timeout when changing PHP tell me there is something odd...

MultiPHP: PHP 7.2 / PHP 7.3
Apache 2.4
EasyApache 4

/etc/redhat-release:CentOS release 6.10 (Final)
/usr/local/cpanel/version:11.82.0.9
/var/cpanel/envtype:standard
CPANEL=release

After further research, seems the problem is around the AutoSSL certificate. With PingDom, SSL is 19s for loading! But not always...

What if anything is noted in the Apache error log? You can find it at /etc/apache2/logs/error_log you may also want to check the PHP-FPM error log [I]/opt/cpanel/ea-php$$/root/usr/var/log/php-fpm/error.log[/I]
