Now I'm facing anothher issue. I would like to access my Nextcloud instance via (for example) https://www.domain.duckdns.org:2222.
For that, I've forwarded port 2222 to port 443 on my router, as Nextcloud and letsencrypt are accessed on port 443. But it doesn't seem to be sufficient, I've got a timeout error when trying to access Nextcloud on port 2222 and even from my local network.
Where am I wrong? Do I have to change some settings somewhere on nextcloud and/or letsencrypt? Or even to rebuild the containers?
