Alles anzeigenI think I see where the problem is:
You are forwarding our public IP (80,443) to 192.168.25.21 (90, 450) which is the nginx proxy manager
Then you ask the nginx proxy manager to forwart 192.168.25.21 (90, 450) to 192.168.25.21 (90, 450) (this is a loop, making nginx proxy manager forward to itself)
nginx proxy manager should forward to 192.168.25.21:443 (which is nextcloud) You do not have a http port for nextcloud.
But setting up swag with a tutorial supported here is the better idea.
The guide is here: [How-To] Nextcloud with swag (Letsencrypt) using OMV and docker-compose
Thank you Zoki. I'll try this tutorial and the port modification you suggested.
