Calibre-web plugin doesn't restart properly

[idefy]

Problem:
When stopping and starting the plugin or restarting the NAS, the plugin doesn't start the server at all.
I haven't found any errors in the logs.

workaround:
I can manually start it by going into the calibre-web jail sheel, then execute this: /usr/local/app/calibre-web # nohup python3 cps.py

Expectation:
The manual step to start the server shouldn't be needed.

To Reproduce:
Follow steps described here: https://github.com/janeczku/calibre-web/wiki/How-To:-Install-on-True-NAS
Check that calibre-web is accessible before step 9
After stopping and starting Calibre-web, the plugin will appear up, but actually the server is not up.
The same happens if you shut down TrueNAS and restart it after.

The only solution I found is to start it manually, which is not expected.

I've tried on and off for years to fix this and never had much luck. Even setting the sysrc to =YES doesn't seem to get it to start automatically.

The only auto start I've found is to use an cron task in the main TrueNAS GUI that initiates a iocage exec calibre /manual-start/calibre-start.sh and making a script at that location that calls the service to start.

However, I don't know how to automate that in a plug-in so I've never submitted it as a fix.

This only works for the initial server start but if I'm cycling the jail I don't find it hard to send that command myself from the shell.

You might be able to directly have the main TrueNAS GUI > Tasks > Cron Jobs call to iocage exec <calibrejailname> service calibre_web start but I haven't tried it as the script worked before I got to that attempt.
