While streaming Hulu, you may face various error codes. The main drawback with those Hulu error codes is that they don’t explain the cause behind the issue or error. If your device fails to connect with the Hulu server while playing a movie, you’ll get the RUNUNK13 error code on your screen. The issue behind the error would be network troubles, Hulu server downtime, errors in the Hulu app, etc. However, the error can be fixed easily with some troubleshooting techniques.
Check Internet Connection
The slow internet connection could be the reason for the Hulu code rununk13 problem. As a result, conducting a speed test will be beneficial. For streaming TV series and movies on this app, a speed of 3.0 Mbps is usually suggested. The required speeds for broadcasting live events and 4k material are 8.0 Mbps and 16.0 Mbps, respectively. If the internet connection is less than 3.0 Mbps, upgrading your service is the best option.
 If you’re on a wireless network, get your phone, computer, or streaming device closer to the router (or vice versa). Restarting your router can potentially increase your connection speed and resolve network-related issues that may be creating the RUNUNK13 Hulu error code.
 If your connection speed continues to be sluggish, notify your internet service provider.
Check Server Status of Hulu
Before troubleshooting other possible causes, use online-based site monitoring tools like DownDetector to see whether Hulu servers are running properly. The tool will intimate if there are issues with the Hulu server. In those situations, wait for Hulu to fix the issue and then start streaming.
Try a New Browser or Device
Try to stream Hulu on a different device or browser to check for the error. If it streams without any error, the issue is with the device you used earlier. In those situations, try the next troubleshooting technique. If the error appears on the new device, you have to wait for Hulu to fix the issue.
Restart Your Device
A simple restart will fix most of the temporary issues associated with the device. Restart the device that you’re using to stream Hulu and then check for the error. If the error continues even after restart, try the next troubleshooting solution.
Clear Hulu App and Browser Cache
Clearing the cached data of the Hulu app is the next solution you have to try out. Too much-cached data may prevent the app from working properly.
Android Smartphone & Smart TV: Settings → Apps → See all Apps → Hulu → Storage & cache → Clear Data → Clear Cache.
Firestick: Settings → Applications → Manage Installed Applications → Hulu → Clear Cache.
iPhone & iPad: Unfortunately, you can’t clear the cache data on Apple devices. Instead, uninstall the Hulu app and re-install it from the Store to fix the issue immediately.
Those who are using the web version clear the Hulu cache files on the browser to stream Hulu without the RUNUNK13 error code.
