Live stream does not work in a restricted network

[kobezf]

I am trying to start live stream in a restricted network with GoPRO HERO 13. I tried to use my embedded Linux device with the sim-card that has a limited access to the internet as a WiFi hotspot, but the camera does not see WiFi network at all. Then I tried to use my mobile phone as a hotspot and the camera was able to see it, but it wasn't able to connect to it. Here is the log file from my application:

Oct 08 13:27:02 live-stream[2261]: [warning] 'EF:33:39:DF:51:CF': cannot connect to wifi 7, reconnecting...

So my questions are:

1. Why camera does not see the WiFi network? Are there any requirements to the network?
2. Why it cannot connect to the network?

Thank you
