Discovery+ App Issues on Samsung TV: What to Do?

Follow these steps in order until Discovery Plus works again:

Power Cycle Your Devices

Power Socket

If the above steps haven’t helped, try power cycling your devices:

  • Unplug your TV and router from power for 2 minutes.
  • Plug them back in and power them on.
  • Test Discovery Plus again.
  • Power cycling often resolves temporary glitches and clears any accumulated data cache/errors.

Check Internet Connection

The first thing to check is your internet connection.

  • Run a speed test on a computer/mobile device connected to the same network as your Samsung TV.
  • You’ll need at least 5-8 Mbps download speeds for streaming Discovery Plus in HD quality.
  • If the speed test shows lower speeds, try resetting your router and connecting your TV via ethernet if possible.

Internet Speed Test

Check Supported Devices

  • Discovery Plus officially supports 2016 or newer Samsung smart TVs.
  • If your model is older, try casting from a phone instead of using the native app.

Check Account Login Details

  • Open the Discovery Plus app and select Sign Out.
  • Then, sign back in with your username and password.
  • Reset password if forgotten. This eliminates login issues.

Delete and Reinstall the Discovery Plus App
