Domoticz on Synology NAS stopped working

[Chris12]

Hi,

My domoticz has stopped working since a couple of days. I noticed that when my dashticz screen was keeping in the refresh screen.
By checking the domoticz website, that was unavailable too. In my synology I can see that the packages has stopped running.
When restarting, the package stopped right away.

The package I'm currently running for domoticz is the Jadahl version 2020.2.12731-8 (last/latest one I believe).

I think the domoticz package has stopped working after my synology has updated some other packages last week.
Not sure which ones are updated, but I remember it was python 3.8 (also running python 2.7 and 3.7 as a package), MariaDB and MyPHPadmin.
I allready removed python 3.8 to see if domoticz will start again, but unfortunatelly not.

How can I troubleshoot this issue? I have got root access to my NAS, so I can do "CLI stuff" to investigate.
But I'm not sure where to find the logfile of domoticz to actually see some more info what is causing this issue.

My DSM version (Synology OS) is 6.2.4-25556, so not on the DSM7 release yet.

I want to re-install the domoticz package if needed, but then I first have to find out where to find the domoticz database and dzvents script files for keeping all my settings and devices. Unfortunatelly the domoticz webpage is not working otherwise I could have done a backup there.

Maybe switching to a docker installed domoticz I can do as well directly, but then I want to have first of all the scripts and backup/database file.

Who can help me out, or point me towards the right direction?

Some more info I have collected using winscp. I located the logfile of domoticz (and found the domoticz.db database and script files as well as the daily/hourly backups.

I found out that my domoticz stopped working on 2021-04-02 20:57:24.342, after that all my devices gives errors like ".....thread seems to have ended unexpectedly"

When examing the logfile after a start of the domoticz package I can see the following:

on the forum here I found some cli commands:

So it seems that the ports 8084 are claimed by another programm or something?

Now that I have all data/settings, I tried to reinstall the domoticz package (first uninstalled) using domoticz_avoton-6.2_2020.2.12731-8.spk downloaded form jadahl website.

The installation goes fine, I let all setings for the ports default (8443/8084)
But after the installation domoticz still does not want to run.

Problem solved! By uninstall domoticz package, after that rebooted my NAS, and re-installed the domoticz package using another port (8484 instead of 8084). After that domoticz worked fine. So next I uninstalled domoticz again, and re-installed is using the default ports. Domoticz now runs fine!

Restored my database file, manually installed some plugins and scripts. Everything seems to be OK right now.
