Howdy user_4wk3tq, and thanks for reaching out in our community! We definitely don't want you to miss a second of your TV time, especially with the World Cup going on, so we'll do everything we can to get you back online 👍 The XRE-00021 error code usually indicates a temporary channel tuning issue. To resolve it, try the following steps:

  1. Ensure all TV connections are secure.
  2. Select **Try Again** on-screen.
  3. Change to another channel using the channel up or down button, then switch back.
  4. Restart the X1 TV Box by unplugging it for 1-2 minutes, then plugging it back in.

I would also reccomend attempting to troubleshoot directly through the Xfinity app if you have not already as it can help resolve a lot of common X1 TV issues as well 🙌 Please let us know if the issues persist!
