Is your HBO Max app acting sluggish? Well, you’re not alone. After asking around, we’ve found out that this is a common issue among subscribers and that there are many possible reasons for this.

So, why is HBO Max so slow? Here is what I discovered!

Why Is HBO Max So Slow?

1. Bugs On The App

Like all applications and services, bugs or cache could mess up your video streaming experience. It’s almost inevitable, but the good news is that this problem can be easily fixed.

Try clearing app data and cache or uninstalling and reinstalling the app. Most of the time, all it needs is a simple refresh.

2. Bugs On The Browser

If you’re streaming on HBO Max on your computer, try clearing the cache. Your browser could get a little overwhelmed when it’s keeping a lot of temporary files.

Here’s how to do this on Google Chrome:

  • Open a window or tab.
  • On the top right corner, click on the three stacked dots.
  • Select Clear Browsing Data under the More Tools tab.
  • Tick the boxes next to Cookies and Other Site Data.
  • Tick the boxes next to Cached Images and Files.

This should make more room in your device, as well as free up some random access memory (RAM).

Alternatively, disabling extensions might just improve the HBO Max app’s performance. These third-party apps may be helpful for some functions, but they also use up a bit of RAM.

Try this method and see if freeing up some RAM this way would do the trick. After clearing the data and cache, try logging out of your HBO Max account. Then, log back in.

Remember that this process will remove saved passwords as well. This isn’t recommended for you if you have a habit of forgetting your password!

3. Slow or Unreliable Internet Connections

For video streaming to run smoothly, a fast and stable internet connection is required. So, if your HBO Max is constantly buffering, slow internet could be at fault.

Try resetting your router by turning it off, waiting ten seconds, and turning it back on again. Then, reconnect to this network once the router’s ready.

If the service is still down, try connecting to a different network if available. The stronger the connection, the better.

4. Running Performance-Intensive VPN

The main appeal behind using a virtual private network (VPN) is to protect you from spyware and potential hackers by obscuring your IP address. However, it could also affect apps’ performance because it’s frequently screening the networks you’re connected to.

When using a VPN, you can expect a 10% to 20% drop in your internet speed, which is probably why HBO Max is acting up. Alternatively, you may also be having the issue because an unwanted network or activity is interfering with your video streaming.

The tricky part here is that you can either fix this issue by disabling VPN or enabling it. So, you’re going to need to do this simple trial and error to find out which one solves the problem.

5. Using Outdated Software

Using Outdated Software

Besides the app versions, your phone’s operating system (OS) must also be up-to-date. So, don’t ignore the prompt that says there’s an update available.

To download the latest Android software, follow the following steps:

  • Open Settings
  • Select System Update
  • Follow on-screen instructions on how to download and install the necessary files

Once you’ve installed the latest software updates, you can enjoy your favorite HBO shows seamlessly.

6. Unsupported Device

HBO Max has hardware and software requirements in order to work smoothly. Unfortunately, this means that not all smartphones are compatible with the HBO Max app.

Verify first if your phone’s among its compatible devices before getting your hopes up.

7. Corrupted Installation Files

This is one of the most overlooked causes of a sluggish streaming service. Because we can’t see every step of the installation process, the ordinary user won’t know that corrupted files are the culprit.

Usually, this happens when the installation gets interrupted, possibly by an intermittent connection or a sudden device shutdown.

To resolve this, uninstall the HBO Max app, then reinstall it again. Make sure you have enough phone battery and a stable internet connection this time.

8. Malware and Viruses

If you’re guilty of downloading files, photos, or apps without verifying the author or developer’s reputation, then lagging apps shouldn’t come as a surprise. You must’ve invited some unwanted guests somewhere along the way.

Make sure you only download verified applications from official websites. Also, be wary of pirated applications and sketchy developers, even in Google PlayStore.

Additionally, you can regularly check for malware by doing the following:

  • On the Google PlayStore app, tap Menu
  • Select Play Protect
  • Tap Scan

The obvious remedy is a trusted antivirus app for mobile phones. Then, for good measure and added security, follow responsible practices on phone usage.

9. Faulty Servers

If everything’s good on your end (supported device, updated software, lightning speed internet) but HBO Max just won’t cooperate, then the servers could be down.

HBO could be fixing those bugs we mentioned earlier or doing maintenance work to improve their service. Unfortunately, with this kind of issue, there really isn’t much you can do except wait until they fix it.


Lagging is a common issue reported by HBO Max users. This could be frustrating, especially when you’re trying to make the most of your well-deserved R&R with some screen time.

So, why is HBO Max so slow?

The right diagnosis will narrow down the troubleshooting options for you. To take the guesswork out of it, try to identify the closest possible reasons for the jam and start there.

If none of the methods mentioned above work, try contacting HBO Max support to report the issue and wait for any instructions or updates.
