How to Fix HBO Max Error Code 1300799?
This error usually appears when something interrupts playback between your device, your internet connection, and HBO Max servers. Sometimes the app needs a refresh. Other times, the network or device causes the issue.
Try each fix below one at a time. After every fix, try playing the same video again.
Fix #1: Restart the HBO Max App
HBO Max error code 1300799 often shows up when the app stays open for too long. Small glitches build up in the background, and playback fails. Restarting the app clears temporary memory and reloads fresh data. When the app opens again, it usually reconnects properly and starts playing content.
Fix #2: Check Your Internet Connection Stability
Streaming needs a steady connection, not just fast speed. Short Wi-Fi drops or weak signals can interrupt video loading and trigger this error.
If your connection becomes stable again, playback often works without changing anything else. Make sure your device stays connected without interruptions while streaming.
Fix #3: Clear HBO Max App Cache and Data
Corrupted cache files can block video loading and cause playback errors.
Follow the steps below to easily clear the app cache:
- Open your device settings
- Go to Apps or Applications
- Select HBO Max
- Open Storage
- Clear cache
- Close settings and reopen the app
On smart TVs, uninstalling and reinstalling the app does the same thing.
Fix #4: Update the HBO Max App
An outdated app version may fail to work with recent service updates. Updates fix bugs and improve compatibility.
Here’s how you can update the HBO Max app in just a few seconds:
- Open your app store
- Search for HBO Max
- Check if an update is available
- Install the update
- Restart the app
- Try playing the video again
Keeping the app updated prevents many playback problems.
Fix #5: Turn Off VPN or Proxy Services
HBO Max checks your location before allowing playback. VPNs and proxy services can interfere with this check and cause error code 1300799. Turning them off allows the app to confirm access correctly and restore normal streaming.
Fix #6: Restart Your Streaming Device or Smart TV
Devices store temporary system data while running. Over time, that data can conflict with apps and block playback.
You can restart your device by turning it off, unplugging it for one minute, and then turning it back on. This refreshes system memory and clears background conflicts that may cause the error.
