I would welcome any pointers for how to debug / fix my inability to connect the iOS Jitsi Meet client to my self-hosted Jitsi server.
The server is Debian 9, and I installed the Jitsi stack using https://jitsi.org/downloads/ubuntu-debian-installations-instructions/
It has direct IPv6 and NAT’d IPv4, and I can connect successfully using either from both internal and external clients via browser.
I have generated a LetsEncrypt certificate for the main sub-domain, and that too is working fine in browsers.
I have configured authentication (following the “secure domain” example at https://github.com/jitsi/jicofo).
I have installed the Jitsi Meet app on my iPhone 6S running iOS 10.3.3.
When I just enter the room name “test”, so using the hosted public version of Jitsi, it works.
When I enter my own server’s details (e.g. “https://sub-domain.domain.tld/room”), I get just a black screen.
I have also tried visiting the page in Safari, then using the link to open Jitsi Meet, with the same result.
I am not sure how to debug this, or even where to look in to log files to see what might (or might not) be happening or if, perhaps because of the “secure domain” setup, it is just not going to happen, and I would welcome any pointers.
