Not receiving messages from remote server

Has anyone run into an issue running wrtc or wrtc star or direct where messages published from a libp2p node running on a remote js server on AWS for example are never received by other peers in browsers or local servers. I have a browser app and 1 server app – these all work fine on local lan

all can publish and receive messages on topics fine

when i deploy the server to AWS it runs OK, but no published messages from it or to it are received / sent – there are NO errors from this.
