Old LEMP stack WordPress site won't deploy any more
I've inherited a WordPress 5.7 site running on an Ubuntu 16.04.3 x64 droplet, which uses a separate DigitalOcean managed MySQL 8 database.
The WordPress site is a Trellis LEMP stack site. PHP version 7.3, but Nginx seems to be using 7.1 from a phpinfo().
I'm aware that all the versions are seriously outdated and need updating, but in the very immediate term I need to first get things working.
There was a database connection error (see https://www.digitalocean.com/community/questions/since-a-wordpress-url-change-i-can-t-connect-to-do-managed-mysql-database) and this involved me trying a lot of unwise things until now the deployment to the staging site via Trellis fails.
Here's what it says:
TASK [deploy : Reload php-fpm] *************************************************************************************** System info: Ansible 2.7.0; Linux Trellis at "Switch from .dev to .test" --------------------------------------------------- fatal: [staging.mywebsite.co.uk]: FAILED! => {"changed": true, "cmd": "sudo service php7.3-fpm reload", "delta": "0:00:00.030313", "end": "2021-12-21 11:51:06.490541", "msg": "non-zero return code", "rc": 1, "start": "2021-12-21 11:51:06.460228", "stderr": "php7.3-fpm.service is not active, cannot reload.", "stderr_lines": ["php7.3-fpm.service is not active, cannot reload."], "stdout": "", "stdout_lines": []} to retry, use: --limit @/home/ubuntu/mywebsite.co.uk/trellis/deploy.retry
If I SSH in and try to start the service I get

Here's systemctl status php7.3-fpm.service:

And I am stuck. I'm not very confident in a Linux environment so I'm completely lost to be honest. I figure I need to fix this before I fix my database connection error!
I did try to add PHP 7.4, but this generated several pages of red errors when I tried to deploy the site so I removed it.
This is a staging site, so it's not critical, but obviously the production site has the same background setup to I'm terrified it will break too!
In the longer term I plan to upgrade everything but would really like some help trying to get it working in the immediate short-term.
Thanks!
It clearly says that php-fpm7.3 fails to start because ERROR: Another FPM instance seems to already. You probably have php-fpm7.1 already running.
