Hi ,
I have installed nextcloud AIO on Debian 12 inside Docker (docker in an LXC). I’ve also installed a seperate LXC with nginx (version 1.22.1). Both of these run in my proxmox environment.
The goal is to install nextcloud and auth using authentik. I have a public domain, not via cloudflare, for which i’ve set an A record to my home server, subdomains were add, using the same A record.
nginx has been configured to serve both authentik and nextcloud. The issue i’m having is that when i connect to my subdomain: nextcloud.domain.nl using port 8444, the full URL has to be: https://nextcloud.domain.nl:8444/apps/dashboard. If i go to https://nextcloud.domain.nl:8444 it will resolve to https://nextcloud.domain.nl/apps/dashboard/ .. which will throw an error “refused to connect”.
To fix this issue I was under the impression i had to change the config.php, i changed the :
‘overwritehost’ => ‘nextcloud.domain.nl:8444’
But that does not help.
To prevent issues locally, i have configured OPNSense with a DNS overwrite, to send nextcloud.domain.nl to my local proxy IP, if i don’t, OPNsense will state i’m doing a DNS rebind attack.
What i would like to achieve is being able to provide the URL : https://nextcloud.domain.nl:8444 and ensure that the base URL remains the same so that i don’t have to type /apps/dashboard.
Also, any configuration i do in config.php seems to revert back to default settings after a reboot/restart of all containers.
