The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 13.3.1
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 24.04.4 LTS
  • Web server and version (e.g, Apache 2.4.25):
    • Apache 2.4.68
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • caddy via caddy geoblocking community plugin
  • Is this the first time you’ve seen this error? (Yes / No):
    • yes
  • When did this problem seem to first start?
    • today
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • AIO
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • no

Summary of the issue you are facing:

I setup my nextcloud a month or so ago, and it has been running fine for me until just now. I uploaded a few files to my jellyfin (I’m using the jellyfin community plugin), then felt hungry and decided to go and make dinner. When I returned from making dinner, my nextcloud and jellyfin were both inaccessible, attempts to access them either via their addresses or locally via the ip address did not work, the only thing I was able to access was the admin page on port 8080, everything else timed out. Here all containers claimed to be running fine, and I could not find any errors reported in the logfiles.

I have restarted my server, I have restarted nextcloud, I have restarted my router, but none of those fixed the problem. I can ssh into the server itself just fine, and everything seems to be running okay there, too.

I am admittedly primarily an electrical engineer dabbling in software for fun, so there is probably something I have missed, but at this point I find myself quite bemused, and really hope there is some kind human out there who can help me out a little :).

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

<?php
$CONFIG = array (
  'one-click-instance' => true,
  'one-click-instance.user-limit' => 100,
  'update_channel' => 'stable',
);

Hi

What happens when you

  • ping the web address?
  • ping the local IP address?

Do the packets go through, or are they lost?

Thank you for reading, but for unknown reasons it appeared to work fine again the next day, so I think for now I will just cross my fingers and hope whatever it was doesn’t happen again
