If you're experiencing issues using HBO GO and Chromecast on your iPhone, iPad, or iPod touch, try the following steps:

Step 1: Update your software

  • Make sure you have the latest version of HBO GO. To do this, open the App Store on your iOS device and search for HBO GO to see if an app update is available.
  • Make sure that your iOS software is up to date by going to Settings > General > Software UpdateLearn how to update

Step 2: Check your internet connection

To stream HD video, you need a high-speed connection with a minimum download speed of 5 Mbps for HD video.

When streaming video, HBO GO adjusts the video quality based on the strength of your network bandwidth and connection speed. If the network bandwidth is too low or the connection speed fluctuates, you might get a lower resolution video or no video. If your Internet connection drops altogether, the video will stop playing and you'll be prompted to reconnect.

To check your network speed, search for “speed test” in a browser, then select RUN SPEED TEST or Start.

If your network speed is above 5 mbps, your connection is fast enough for HBO GO. To keep troubleshooting, move onto Step 3.

If your network speed is below 5 mbps, try accessing HBO GO on another device, to make sure it’s the network and not just your device that’s having a problem. If the other device works fine, move to Step 3. If it also has trouble connecting to HBO GO, follow these steps to try and increase your network speed.

  1. Reduce traffic on your Wi-Fi network - Try minimizing the number of devices using your Internet connection when you watch HBO GO. This will allocate as much bandwidth as possible for streaming HBO GO.
  2. Restart network Wi-Fi devices - As a last resort, try restarting your network devices. Unplug your modem and router, wait one minute, then plug them back in.

Note: Your iOS device and Chromecast must be connected to the same Wi-Fi network.

Step 3: Restart your devices

  1. Unplug the power cord from your Chromecast device.
  2. Restart your iOS device.
  3. Plug in your Chromecast device.
  4. Make sure that both your iOS device and Chromecast are connected to the same Wi-Fi network (go to Settings >Wi-Fi on your device, and choose a network).   
  5. Try casting a video.

Step 4: Delete and reinstall HBO GO

  1. Delete the HBO GO app from your iOS device. To find out how, please see Delete an app.
  2. Open the App Store and install the HBO GO app.
  3. Open HBO GO and sign in again.
