I have Echo Hub (Echo Ship 1503/155) and Reolink NVR. I have verified all the RTSP Streams URLs. Monocle Gateway reverse proxy works. I can connect to it via openssl s_client as well. But, I cannot get Alexa to show my cameras. It tries to connect for 10sec and then says that the camera are not working. I have tried @tunnel, @proxy, @proxy-tcp but no success. Please help me in this.
