There are some potential causes of the Error Code 100. As I mentioned above, the glitch may hide in your device, the Internet and even the Max account. Follow these steps to fix the Error Code 100 on HBO Max quickly.

Reason 1
An Outdated HBO Max App

If you face the hurdle of the HBO Max app not working on your phones or Smart TVs, the possible reason is an old version HBO Max app. Outdated apps may work for some time, but will keep irritating you with HBO Max error code 100.

Reason 3

Reason 4

Another possibility of Error Code 100 is an incompatible device or an outdated browser version. For example, if you encounter the issue when using Chromecast or a webpage, it means that the version or your Chromecast or browser is no longer supported.

Issues in Server

People frequently ask why HBO Max is so slow. Well, the issue could be anywhere. However, if your internet is stable and you are still facing this HBO Max error, maybe the server is down.

Fix HBO Max Error Code 100 Quickly

What is Error Code 100 on HBO Max? Now it's pretty clear. Let's explore how to fix the problem quickly step by step.

Fix 1: Get a Strong Internet Connection

Your internet speed should be at least 5Mbps to run HD videos. Make sure that your Internet speed performs better than the standard, so that you can enjoy streaming on HBO Max without any worries, or you will end up with error code 100.

Restarting or upgrading your modem are both good methods to improve the internet connection.

Fix 2: Update Your HBO Max App

Error code 100 can also be a common reason for your HBO Max app not working. When it comes to the app, the possible reason could be an outdated one.

Update Your HBO Max App

Updating your app is the best solution for this enigma. It will help refresh the content and upgrade many features, enabling errorless streaming.

  • On your device, go to Apps > Settings > Updates. Now look for the HBO Max app and click on the update option.
  • For Android and iOS, go to the Play Store or App Store and update manually from there.

Fix 3: Check for HBO Max Server

Sometimes, the problem may occur on the Max server side. Under such a circumstance, there is nothing you can do about a down server other than to wait.

You can go to a detector site such as Downdetector to see the real-time status of the Max server. I recommend this site because you can also check the latest posts from Max on X (Twitter).

Fix 4: Clear Cache

Clearing the cache on your browser and streaming devices can free up some space and eliminate the error code 100.

  • For a Smart TV, go to Settings and then Apps. Look for the HBO Max app, select it and choose the clear cache option.
  • For Smartphones, go to Settings > Apps > HBO Max. Look for the option of Clear Cache and Storage > Clear cache.

Fix 5: Turn Off or Change Your VPN

Using a VPN can lead to a permanent ban on your account. Hiding your location through a VPN or a proxy server can lead to repeated error code 100. Turn off your VPN from settings and then load HBO Max.

If you still want to watch HBO Max outside its service regions, you can choose another reliable VPN, such as ExpressVPN. It's said that it can solve the problem by following these steps:

  1. Use a local payment method when signing up for Max.
  2. Clear your browser’s history and cache.
  3. Try switching to a different ExpressVPN server.
  4. Watch HBO Max using a different web browser.
  5. Make sure your streaming app, web browser, and VPN are all updated to the latest version.
