My Fire TV isn’t showing up in the list
The usual cause is that your iPhone and Fire TV are on different
networks. Check that both use the same Wi‑Fi name — some routers
split 2.4 GHz and 5 GHz into separate names. After confirming, run
discovery again in the app. Also enable Local Network for the app
in Settings → Privacy & Security → Local Network.
It worked before, but the TV disappeared
Your TV may have received a new IP address from the router.
Restart the Fire TV, wait until it is back online, then try again.
If it keeps happening, restart the router or assign a static IP to
the TV in your router settings.
Scan runs a long time and finds nothing
Disable any VPN or proxy on the iPhone and scan again. On your
router, turn off “AP isolation,” “client isolation,” or “guest
network isolation” if those features block devices from seeing
each other on the same LAN.
