Getting "mqtt connection error" when using iPhone as nrf Cloud gateway

[Andreas Rübner Johnsen]

I'm trying to use an iPhone as gateway for nrf Cloud. The user is "Verified" and the "Gateway Name" is the same in the app as the only gateway I have in the nrf Cloud. But the gateway does not connect. From nrf Cloud I get the message "Your gateway is disconnected." and the log in the app has the following entries:

• "connecting",
• "mqtt connecting",
• "mqtt connection error".

The last entry with the following details ""mqtt client state changed to: connection Error".

The app is version 1.1.0 build 101 on an iPhone XS iOS version 12.1.2.

I does however work with my iPad running iOS 11.03. But I still want it to work with an iPhone :-)
