The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • Nextcloud AIO v11.3.0
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 24.04.2 LTS
  • Web server and version (e.g, Apache 2.4.25):
    • Apache/2.4.63 (Unix)
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • unknown
  • PHP version (e.g, 8.3):
    • 8.3.22
  • Is this the first time you’ve seen this error? (Yes / No):
    • No
  • When did this problem seem to first start?
    • initial installation
  • 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:

Talk has never worked on this stand-alone instance of NextCloud. Notify-Push log states, ERROR [notify_push] src/main.rs:84: Self test failed: Error while communicating with nextcloud instance: error sending request for url.

When initially installing NextCloud, I disabled reverse DNS lookup in order to complete installation.

This is a sandbox system I’m using to learn NextCloud administration as I’ve been tasked to admin a 100 user installation on a dedicated server with an ISP. Talk is running on that instance, and they want a HPB and are willing to pay for a second dedicated server. I prefer to use Docker and maybe Docker compose to include a reverse proxy and HPB. The long term goal will be to replace the current instance with NextCloud AIO and point to the existing data and MySql databases. What is the best way to enable Talk on my stand-alone instance and move forward with the hosted instance?

Steps to replicate it (hint: details matter!):

Install NextCloud AIO from GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance.

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

Ok, so as already guessed, the instance cannot reach itself using the configured domain. That means hairpinning (nat loopback) or split-brain dns is not working in your network. See GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance. for a solution

Note: this and the linked solution are a fix for AIO on Ubuntu (24.04) and may not apply to other installations.

While researching this issue, I came across this discussion, Web server can connect to itself. #6096. After changing the /etc/hosts and /etc/hostnames files, and rebooting the server, still no luck. Today, I was reviewing with the team lead and I wasn’t seeing the same errors about not connected in the logs, and Talk is working as well as Collabra! curl -I https://myDomain was failing last night, and today it’s working. I’m not sure how or why, but that’s besides the point :grinning_face:

We tested everything with 3 participants on a video call and it was working great. Next steps are adding a HPB running in another container, and restoring backups of data and db from our production box, with the goal being to replace the existing instance with AIO. That’s the plan, anyway. Glad to get over the first hurdle. Hope this helps someone with the same issue.
