Streaming your favourite show only to find out that HBO Max not working can be really irritating. Whether the app won’t load, or crashes out of nowhere. These problems are more common than one might expect, but are usually pretty simple to resolve. This complete guide will walk you through the most common HBO Max problems and what each of the error codes actually means, with practical solutions to quickly get you back on your way to watching free of error and frustration.

Why is HBO Max Not Working?


There can be several reasons why it won’t work. While it can be very irritating, these problems are actually quite common and can also be easily fixed. Below are some practical solutions to help you fix it.

  • Test your internet connection. The app won’t work if your connection is weak or unstable and might even get stuck while loading. If that’s the case, switch to a different network or reboot your Wi-Fi router.
  • Update the HBO Max app. It can crash frequently and not load shows and movies if you have an older version. Head over to App Store or Google Play and update it to the latest version.
  • Restart your device. It can sometimes work to reboot your device or smart TV to clear temporary bugs that could be causing the app to misbehave.
  • Clear the app cache (Android/TV) or reinstall the app (iOS). Clearing out or resetting the app can get rid of loading errors and make the app behave properly.
  • Check if HBO Max is down. It can sometimes be their end (their server is down). You can check sites like Downdetector.com to see if other users are experiencing the problem too. If HBO Max is down, then the only thing you can do is wait.

Try these steps one by one, and you’ll most likely be able to fix HBO Max not working.
