Cant connect to my node using ZAP when on mobile network

[adolfosrs]

Describe the bug
I'm being able to connect remotely to my node using Zap when I'm on a regular wi-fi connection (not local). But I'm not being able to connect when trying it on a mobile 4G network.

I'm on a complete different network when trying the wifi approach. And I'm also being able to ssh through the 4G connection but when trying to connect using zap the app refuses to connect.

When trying to scan the lndconnect QR code with my phone already on the mobile network I get the following:

Could not connect to server. (Name resolution failure)

To Reproduce

1. Try to connect to the node on a 4G mobile network
2. Connetion fails and app shows nodes list screen.

Expected behavior
Zap should connect to my node when I'm on a mobile 4G network

Your environment

• Device: iPhone 7
• OS: iOS 12.2
• Version: 0.4.0 build: 46

Additional context

I'm currently using a DynamicDNS from http://freedns.afraid.org

can you try to quit the app (by swiping up on the app's preview) and start again when already connected to 4G?

I know there are some issues related to switching from wifi to 4g

@ottosuess Does not work. The app just goes directly to the nodes list screen and there is no way I can access the node.
