Domoticz stays offline

[veganbels]

I updated Domoticz with a version that is higher then available via Synology (4.0.10000) instead of (4.9700) as it worked not as I hoped.

I get an error on my NAS 214Play on the used port (8084).

I want to change the port but as the package stay offline, I de-installed the package and installed it again. But the package stays offline.

How can I solve this?
