Cannot access AppStore

ℹ️ Support
,
1

I installed NextCloud latest version. Application work fine but I cannot see any Application in AppStore to add new Applications.
Due to local restriction (China), the only way to access from Internet is through reverse proxy. I’m using Cloudflare Tunnel with Cloudflare SSL certificates.

  • Nextcloud Server version (e.g., 29.x.x):
    • 31.0.4
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 24.04
  • Web server and version (e.g, Apache 2.4.25):
    • Apache 2.4.58
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • CloudFlared latest
  • PHP version (e.g, 8.3):
    • 8.3.6
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • Immediately after installation
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • manual server install with script
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • ONLY CloudFlare Tunnel, with CloudFlare SSl certificate, No TLS et HTTP 2 configured

If you need to configure a proxy for outbound connectivity, use the proxy (and related) configuration directives.

Make sure, that you can access the following URL from your server:
https://apps.nextcloud.com/api/v1

Further information about the available appstore related parameters can be found in the admin guide:

Thanks a lot jtr, I don’t need proxy. Nextcloud website and Nextcloud app store URL can be accessed without VPN (proxy). This server have normal access to Internet without proxy as long as the target website isn’t banned by China Great Firewall.

Clients need to use Cloudflare tunnel to access the server. But the server itself does not use Cloudflare tunnel outside of client requests.

Thanks j-ed, that was the first thing I tested, using a browser and command line curl to access https://apps.nextcloud.com/api/v1 and other failed URL mentioned in log.

As mentionned above, all those URL can be accessed from the server without proxy and the server does not have any proxy configured.

UPDATE:
In fact it was working spontaneously few hours later without any change to configuration. So seems it is more related to potential internet access quality. I will explore parameters to extend requests timeout.

I also faced this issue.
The problem got fixed automatically after few days.

Yes, same experience here and fortunately after few hours not few days. Probably link to unstable network quality.
I guess it will all be about being able to change the timeout in some config. But not time to figure out where to find such parameters.
