Cannot install apps or view the app store

I am running Nextcloud in a docker container, was on v29 but have just upgraded to the latest image on dockerhub (except it’s been updated yet again since I started this!). Also, it’s behind an nginx proxy, in case that’s an issue. Nevertheless, here is what I know:

Docker version: 27.2.1, build 9e34c9b
Docker image: "Created": "2024-09-27T03:21:15.238539109Z"
Nextcloud version (eg, 29.0.5): 30.0.0.14

I’ve turned off my adblocker, and browser extensions.

The issue you are facing:

When I go to the apps/Discover page, I get “Nothing to show”, “Could not load section content from app store”. I also see in the log:

{
  "reqId": "Py3wVUuNs9E6bZAevVIa",
  "level": 2,
  "time": "2024-09-27T09:45:58+00:00",
  "remoteAddr": "192.168.1.61",
  "user": "John",
  "app": "appstoreFetcher",
  "method": "GET",
  "url": "/settings/apps",
  "message": "Could not get apps from the appstore",
  "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36",
  "version": "30.0.0.14",
  "data": {
    "app": "appstoreFetcher"
  },
  "id": "66f67ee99c83a"
}

And if I try to install an app manually:

$ docker exec --user www-data nextcloud php occ app:install notes
Error: Could not download app notes

Is this the first time you’ve seen this error? (Y/N): It wasn’t working in 29 either, which is why I upgraded.

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

That is not the official appstore url - we can’t you help there, sorry.

3

That was a hangover from another thread with a similar problem. I’ve remove that line and still have the same issue. It also wasn’t there when I was using v29.

4

But it is also in the exception? Can you post the current exceptions?

Also after changing, the error might still be cached, it might take a bit until the request is retried.

Gotcha! This is after a restart of the container:

Hm, can you try to manually test the request? Is the container able to connect externally?

Something like curl https://apps.nextcloud.com/api/v1/apps.json ?

7

Pretty sure this is a docker networking issue now:

$  docker exec -it --user www-data nextcloud bash
www-data@<container>:~/html$ curl https://apps.nextcloud.com/api/v1/apps.json
curl: (28) Failed to connect to apps.nextcloud.com port 443 after 131168 ms: Couldn't connect to server
8

OK - it isn’t Docker; the host can’t access that URL either…but my Windoze PC (sitting on the same lan) can…I’ve definitely got some weird networking config issue.

9

OK - maybe a little paranoid of me, but I have geoIP blocking set up on my server; I only allow connections to/from a limited set of countries; Nextcloud’s app server is in Finland. Adding FI to my allow list fixed the problem!
