This guide will walk you through simple and clear troubleshooting steps to resolve HDCP errors on HBO Go. Each step is explained in detail so even beginners can follow along easily. Let’s get started and get your streaming back on track.

By understanding the reasons behind HDCP errors, you can prevent them from occurring in the future. This will help you enjoy seamless streaming without interruptions.

Read through each solution carefully and apply them one by one until the problem is fixed.

Quick Note: Prerequisites and Initial Checks

Before diving into detailed troubleshooting, here are some quick checks to save you time:

  • Check your HDMI cables and connections: Faulty or loose cables can trigger HDCP errors.
  • Restart your device: Sometimes a simple reboot of your Windows 11 PC can clear temporary glitches.
  • Update HBO Go and Windows 11: Make sure both the app and your operating system are fully updated to avoid compatibility issues.
  • Use a compatible browser: HBO Go works best on browsers like Microsoft Edge or Google Chrome on Windows 11.

Step 1: Restart Your PC and HDMI Devices

Restarting your computer and any connected HDMI devices is often the simplest fix. This helps reset the HDCP handshake, which is a communication process between your device and display to verify content protection.

  1. Close the HBO Go app or browser tab.
  2. Turn off your PC completely.
  3. Unplug your HDMI cable from both your PC and monitor or TV.
  4. Wait for about 30 seconds, then reconnect the HDMI cable securely.
  5. Turn your PC back on and launch HBO Go again.

This step ensures that any temporary errors in your HDMI connection or HDCP authentication are cleared.

Step 2: Use a Different HDMI Port or Cable

HDCP errors can sometimes be caused by faulty HDMI ports or cables. Trying a different port or cable can help you identify if hardware is the issue.

  • Switch to another HDMI port on your monitor or TV, if available.
  • Replace the HDMI cable with a new or known-working one.

HDCP requires a secure connection, and damaged cables or ports can break this. Testing with different hardware rules out physical connection problems.

Step 3: Update Graphics Drivers in Windows 11

Outdated or incompatible graphics drivers can cause HDCP errors because they manage video output and HDCP protocols. Keeping them updated is essential.

  1. Press Win + X and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click your graphics card and choose Update driver.
  4. Select Search automatically for drivers.
  5. Follow the prompts to install any updates.
  6. Restart your PC after updating.

Updated drivers ensure your system properly supports HDCP protocols required by streaming services like HBO Go.

Step 4: Clear Browser Cache or Reinstall HBO Go App

If you are using HBO Go through a browser, corrupted cache can cause playback and HDCP issues. Clearing the cache may help.

Clearing Cache in Microsoft Edge:

  1. Open Edge and click the three dots (…) in the top-right corner.
  2. Go to Settings > Privacy, search, and services.
  3. Under Clear browsing data, click Choose what to clear.
  4. Select Cached images and files and Cookies and other site data.
  5. Click Clear now.
  6. Restart the browser and try HBO Go again.

If you use the HBO Go app from the Microsoft Store, try reinstalling it:

  1. Open Settings and go to Apps > Installed apps.
  2. Find HBO Go, click the three dots next to it, and select Uninstall.
  3. Restart your PC.
  4. Download and install the HBO Go app again from the Microsoft Store.

These steps remove corrupted files that could interfere with HDCP authentication.

Step 5: Disable Hardware Acceleration in Your Browser

Hardware acceleration helps improve browser performance but can sometimes conflict with HDCP. Disabling it may resolve playback errors.

To disable in Microsoft Edge:

  1. Open Edge, click the three dots (…) and select Settings.
  2. Go to System and performance.
  3. Turn off the toggle for Use hardware acceleration when available.
  4. Restart the browser and try streaming again.

This forces the browser to handle video decoding via software, which can avoid HDCP issues on some systems.

Step 6: Check Display Settings and Resolution

Incorrect or unsupported display resolutions can cause HDCP errors. Make sure your display settings are compatible with your streaming content.

  1. Right-click on the desktop and select Display settings.
  2. Under Display resolution, choose the recommended resolution for your monitor.
  3. Ensure the refresh rate is set correctly (usually 60Hz for most monitors).
  4. Apply the changes and reopen HBO Go.

Matching your display settings with your hardware capabilities ensures HDCP authentication can work smoothly.

Alternative Methods and Advanced Options

If the above steps don’t work, you can try some advanced options:

  • Use a different browser: Sometimes switching to Google Chrome or Firefox can bypass HDCP issues.
  • Disable VPN or proxy services: VPNs can interfere with content authentication.
  • Update BIOS and chipset drivers: This can resolve deeper hardware compatibility issues.
  • Check for Windows updates: Microsoft often releases fixes for media playback problems.
