Casting from my android device to a chromecast on a specific network, I get an “unable to cast” message on the chromecast screen. This only happens on this specific combination of server/client/chromecast network. I can cast from this server/client to a chromecast on a different network. I can cast from this server to the same chromecast using a different client (Plex Web/chrome). I can cast from a different server to this chromecast using the same client. It affects all files on this server.
Server version: 1.7.1.3856 (although it’s been happening for a while)
OS: Ubuntu 16.04/docker
Clients, w/ versions, if applicable: Android 5.10.1.264
