I want to do the same set up like yours.
How do you use Omv LetsEncrypt plugin and LetsEncrypt Docker at the same time ?
If you forward ports 443&80 from router to Docker, then what ports do use it for the LE plugin ?
sorry for the late Answer,
i bought an old house, so i had no time for OMV
i think i didn't use OMV-LE-Plugin, just the docker. - but i can't check now, because system is offline due to moving...
