I installed with an install script - OMV and "Extras".
I did after installation the let's encrypt certificate - I find it in "General" SSL - now - the OMV shows with my dyndns. domain a proper secure lock.
To be clear - I did not install let's encrypt with docker - I did install through the plugin from the "Extras"
I installed MariaDB and Nextcloud with the videos of "Techno Dad Life" - and everything works after some smaller issues - but managed.
OMV and Nextcloud are up and running. BUT:
But the nextcloud installation don't except /uses the existing certificate (warning entering unsecure website....
Now is my question: How can I include as well my nextcloud-docker-installation - and maybe other docker plugins which might need 443 as well - under the same certificate?
I think there should be a way to add more docker to the same let's encrypt certificate, even if they are installed after it.
