Implementation code does not appear to work

Short story long. I have WordPress installed in a docker container through Portainer on a private NAS.
WordPress itself seems to be working fine, but the scheduled actions are not running and I am lost trying to fix it. Definite newbie at running a NAS.

So, found your Advanced Cron Manager and installed the free version. Now, some scheduled actions execute, many still do not. However, I can come down to ‘action_scheduler_run_queue‘ and hit ‘execute now’ and it runs all scheduled events. Yay! But how can I get this to execute on auto? I do not want to have to go there several times a day and click the button to keep things running.

So, I copied the php implementation code and created a snippet. I used a php snippet plugin to run that snippet on every page. Plugin shows the snippet is there and active. Problem is, the implementation code does not run or just doesn’t do what it is suppose to do. Why?

I know WP in Docker containers has issues running crons and scheduled events. I thought your utility was going to fix that. It sort of does in the fact that I can hit that execute now button and everything runs awesome. But I need a way for that to execute on it’s own. Any ideas?
