The app, which is designed to be used by people who want to watch live streaming from their cameras and video encoders, has a problem. When you try to connect to a live stream, it tells you that the connection is not established.

What is the problem?

It is caused by the app not being able to determine whether the stream is established or not. It tells you that the stream is not found even though you can clearly see the stream.

How can I solve it?

You need to change the setting in the app to allow the app to use the device's Wi-Fi or cellular network. You need to check the box for "Only support old devices".
