Thanks for your feedback about your installation issue. I think it can help other users. By the way, the default with Ubuntu 20.04 is now to use a socket (/run/php/php7.4-fpm.sock) instead of a TCP connection (127.0.0.1:9000). Another solution is to edit your nginx configuration file and use this socket: fastcgi_pass unix:/run/php/php7.4-fpm.sock; Instead of the TCP connection: fastcgi_pass 127.0.0.1:9000;
