While troubleshooting the cURL problem I checked the apache logs and noticed something odd. Although all of my wp sites are set to php-fpm 7.4 inside of ISPConfig.... apcahe believes my sites are actually running fcgi. Code: [Sat Nov 06 13:27:26.538923 2021] [proxy:debug] [pid 3828] proxy_util.c(2383): [client 192.168.0.14:33966] AH00944: connecting fcgi://localhost/var/www/clients/client9/web19/web/wp-admin/admin-ajax.php to localhost:8000, referer: https://subsite6.tester1.example.com/wp-admin/site-health.php [Sat Nov 06 13:27:26.538928 2021] [proxy:debug] [pid 3828] proxy_util.c(2420): [client 192.168.0.14:33966] AH02545: fcgi: has determined UDS as /var/lib/php7.3-fpm/web10.sock, referer: https://subsite6.tester1.example.com/wp-admin/site-health.php [Sat Nov 06 13:27:26.538978 2021] [proxy:debug] [pid 3828] proxy_util.c(2592): [client 192.168.0.14:33966] AH00947: connected /var/www/clients/client9/web19/web/wp-admin/admin-ajax.php to httpd-UDS:0, referer: https://subsite6.tester1.example.com/wp-admin/site-health.php [Sat Nov 06 13:27:26.540331 2021] [proxy:debug] [pid 3828] proxy_util.c(2963): AH02823: FCGI: connection established with Unix domain socket /var/lib/php7.3-fpm/web10.sock (*) Inside of WP... of WP wordfence plugin also believes that I am running fcgi 7.3 ... I know that the base system of the server is php 7.3, but I thought that Domains >> Websites >> PHP / PHP Version was supposed to enable the site to run in the specified version. Confused...
What you posted shows that the site is using php-fpm as the endpoint of the connection is the PHP-FPM socket /var/lib/php7.3-fpm/web10.sock. The apache module that connects apache to php-fpm is named proxy_fcgi and that's where the word fcgi in the debug output comes from.
ok.. thx for the clarification.. I saw fcgi and lost it... Also wordfence is recommending settings based on fcgi, so it was a little counter intuitive .... in any case the real problem is my other post about DNS... I run every test and narrowed the issue to DNS simply not resolving
