The issue you are facing:

Can’t see apps on the AppStore.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Login as Admin
  2. Go to any page that should list appstore apps
  3. Frown at the non-existent list of uninstalled apps.

The output of your Nextcloud log in Admin > Logging:

[appstoreFetcher] Warning: cURL error 49: Couldn't parse CURLOPT_RESOLVE entry '' (see for

GET /settings/apps/list
from **router ip** by admin at 2022-05-20T14:28:53+00:00

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

Turns out I was focused on the wrong error. There was another error pointing to DNS issues and it turns out I didn’t have resolv.conf properly symlinked to work with systemd-resolved. Once I fixed that, it works fine.
