nPlayer Screen Mirroring Icon Disappearing?

[strixton]

Usually when I fire up a file the screen mirroring icon shows up bottom right enabling you to watch a show on your TV (thats on the same network) however recenly my icon shows up for like 1 second then disappears.

Has this happened to anyone elses?

Re-booted modem which sorted the issue, now connects to TV again through the screen cast icon.
