ATEM streaming bridge with other RTMP devices

Hello,
I've setup my streaming bridge on the workshop LAN with 192.168.1.221.
Stream key is set to " password ".
I have got an Ursa broadcast G2 camera, Teradek cube and a Mevo Plus camera that I want to stream to it.
The Ursa broadcast works and I went in to the XML file and found that the URL is rtmp://192.168.1.221/app
Stream key is set to " password ".
I'm trying on both the Teradek cube and Mevo Plus but both aren't able to communicate with the ATEM streaming bride.
The Mevo Plus has spots for URL and key but it comes back unable to connect to RTMP server.
The Teradek, I use primary URL: rtmp://192.168.1.221/app and stream: password
I've also tried rtmp://192.18.1.221:1935/app as the primary URL.
It is set to auto connect but broadcast status reads "reconnecting". The ATEM setup never shows ON AIR nor do I get an image on the connected monitor.
