Hi @Devid and welcome here!
Sometimes app in casaOS/ZimaOS has collision of ports. It is due too many apps on one place…
You can simply change any of ports when You 3 dots click (in casaOS) on Any App, choose (App) Settings . Change port(s) and save. It cause restart of App. It’s OK.
For example:
on Host side, port (http): 8050 mapped inside to the container to port 8080
All apps can be changed this mentioned way. But casaOS frontend (web UI) can be changed only in this way. Click Settings and simply change port:
(only means there is no 3 dots App settings for casaOS)
