I got all parts - but can't put it together.
I managed so far:
OMV5 - up and running on a small HP proliant Server Gen 1 (!) - 1,2GHZ and 8 GB Ram - 2x250mb HDD and 2x1TB HDD - as Raid
A dyndns domain is working too
But - I watched nearly every part of Techno Dad - I see all videos - but nothing matches and I don't understand everything to the last piece.
Of course an video from scratch would be "my" solution - but now I need your help.
How do I make the right connection to get letsencrypt worked in that way, that my dyndns url is called properly on https (green lock in browser) and forwards to my nextcloud docker installation?
