Did someone find any workaround?
In my case on clean OMV 5 network works perfect, no problems.
As soon as Docker and Portainer is installed, on first reboot it looses all network settings.
With omv-firstaid it is possible to put it back only when LAN cable is disconnected.
Is there any way to hard code IP address to system / docker / anything?
Portainer is used for torrents and Plex.
