Device failure occurred. Please restart your device and try again (501.-172).
To fix this error:
Turn your device off, then back on
Turn off your phone or tablet. Make sure it's turned off, not just locked.
Turn it back on.
Try Netflix again.
Restart your home network
Turn off your device, then unplug your modem and router from power.
After 30 seconds, plug in your modem and router.
Wait 1 minute, then turn on your device.
Note: Some devices, modems, and routers might take longer to reconnect to the Internet.
Improve your Wi-Fi signal
To get a better signal you can:
Move your router and your device closer to each other. If possible, put them in the same room.
Move your router away from other wireless devices and appliances.
Keep your router in an open space off the floor. Routers get better reception when on a desk or bookshelf.
Restore your default connection settings
If you've changed the connection settings on your device, you'll need to change them back to default.
These settings could include:
Custom modem settings.
Virtual Private Network (VPN) or proxy service settings.
Custom DNS settings.
If you need help changing these settings, contact the device manufacturer.
Once you've reset these settings, try Netflix again.
