Ubuntu Linux 18.04.4 manged by virtualmin
Nexcloud 20.0.8
PHP 7.4.16

Apache Error log:
Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1:8003

I am not able to figure out the reason. Everything was working normally before updating the PHP modules to the latest updates.

Solution:

Check the log for last 40 lines and saw the error with PHP redis module, before I was only looking last 20 lines and couldn’t find a meaningful error message.

Installed redis module again using

sudo apt-get install php7.4-redis
sudo service php7.0-fpm restart
