it seem the PHP-FPM stopped working, how to fix it?

There is no SOCKET connection in PHP-FPM 7.4 configuration of your MYDOMAIN.COM domain name. For PHP-FPM 7.4 you need to configure php 7.4 to add a plugin for mydoma.com.

systemctl status php-fpm74
if it is stopped, start it
systemctl start php-fpm74
if it's alive, try restarting it
systemctl restart php-fpm74
if that doesn't work, please post the contents of
journalctl -xeu php-fpm74
