I have setup and configured the gateway on my Raspberry Pi and tested the configuration with my Fire TV cube and it shows the cameras on the TV fine.

On the Echo Show 5 (2nd Gen) however it tries to connect and after about 15 seconds says the camera is not responding. As the Fire TV cube is working I know the configuration is correct. I have the resolution set to 1280x720p which is the highest I believe the echo show supports.

Can anyone advise what I may be doing wrong.
