Raspberry pi 3 with latest Ubuntu core and running the latest snap version for raspberry pi of rocket chat. As of writing.
Rocket chat is more or less basic standard installation, nothing custom, with self signed certificate.
I could not use a proper certificate from the built in service because the URL is a sub domain from open dns, which can not be issued https certificates.
I can connect to the server using the url from a browser, from the desktop application and from the android application. But I can not with the iOS app, not even with the latest released today. It just says “oops the url you entered was invalid etc”.
Is it because of the self signed certificate? I have a feeling it is but I don’t know what to do about it. I also heard something about web sockets but I can’t find more info about it.
