Started a brand-new docker image; get error when trying to access it

[amca01]

Because I completely wrecked my Nextcloud/Docker by stupidly trying to upgrade beyond a single version difference (I should have known better) I thought I'd completely remove Nextcloud from my system and start afresh, Which I did, with the apache version 23.0.0, and using traefik as my reverse proxy. This worked well for me in the past.

But now, when I attempt to access Nextcloud remotely, I do at least get a Nextcloud screen, but unfortunately just one which tells me that "The server was unable to complete your request.", and that "More details can be found in the server log.", and I should contact the network administrator. Well, that's me (this is all running on a VPS). Although I've been running this VPS for years, I normally just start up a few things I need and forget about them. So my network-admin abilities are very meagre.

But does this error mean I have to enter the Docker container and ferret about in the apache server log? I imagine that would be the only server of which Nextcloud is aware, so to speak. I have in fact tried to do that, entering the running docker container as root and checking out the /var/log/apache2 directory. But my attempts to view any of error.log or access.log (with any of cat, more, tail) produce nothing: just blankness, which I have to Ctrl-C out from. So if the files are there, I can't find a way of looking at them

Anyway, I've followed all the instructions, and included the values for the mysql passwords, and I've reached an impasse.

I'm mighty confused here. When I set up my initial Nextcloud/Docker container some years ago it just sort of worked. I know my description above is vague, but might anybody have a pointer about what I should look for and where?

Same here, but I am using postgres. I attached logs of both docker containers (app + postgres).

$ docker logs nextcloud_app

Since you mentioned traefik I assume you need to add tweak some settings for the proxy: https://github.com/nextcloud/docker#using-the-apache-image-behind-a-reverse-proxy-and-auto-configure-server-host-and-protocol

Please check the Nexcloud documentation for more details.
