What are Hulu error codes?
Hulu uses a series of alphanumeric codes to flag specific issues with content playback, app functionality, or network connections. While these codes are useful for engineering teams, they can be cryptic for regular users. The codes typically follow a pattern with a prefix (such as P-) and a number or a combination of letters and numbers.
Knowing what each code means can significantly reduce your troubleshooting time and get you back to watching your favorite content. Let’s take a look at some of the most common.
Common Hulu error codes and what they mean
- P-DEV318: One of Hulu’s most common streaming mistakes. This often indicates a problem on Hulu’s side, but it can also be caused by network issues or outdated app software.
- P-DEV320: Another common code that usually indicates device communication issues or playback issues.
- P-TS207: Time-sensitive errors often associated with live streaming or synchronized playback across devices.
- RUNNK13: Usually an error playing content that could be related to cache corruption or server timeout.
- PLAREQ17: Indicates a problem with the video request, usually due to regional restrictions or outdated software.
You may see these errors occur more often on certain devices, such as Roku, Fire TV, smart TVs, or older smartphones with outdated apps or firmware.
So why does P-DEV318 keep happening?
P-DEV318 stands out because it appears on multiple devices and under different conditions. Generally, this error is related to communication issues between Hulu’s servers and your streaming device. That means it could be:
- A network connection problem (weak or intermittent Wi-Fi)
- Hulu’s server is experiencing outages or slowdowns
- Outdated version of the Hulu app on your device
- A compatibility issue between the Hulu app and your operating system
If you’ve tried switching shows or movies and the error still persists, the problem is likely deeper than a single corrupted stream. It may have to do with the way your device talks (or doesn’t talk) to Hulu.
Fix Hulu error codes like P-DEV318
The good news: Many of these issues can be resolved without calling customer support. Here is a step-by-step troubleshooting guide:
1. Check for Hulu server issues
Use a service like Down detector to see if Hulu is dealing with a widespread outage. If the problem is on their side, you should wait until it is resolved.
2. Restart the app and your device
Close the Hulu app completely (don’t just minimize it) and restart your streaming device. Power cycling can resolve many conflicts between apps and systems.
3. Clear the cache and data
Over time, cached data can become corrupted and cause errors. Go to your device settings, find the Hulu app and clear its cache and saved data.
4. Update the Hulu app and device software
Check the app store for Hulu updates and make sure your operating system is current. If your app version and operating system do not match, it may cause playback errors.
5. Switch between devices
If you access Hulu on more than one device, try switching to see if the problem is device specific. This can help determine if the error is related to your streaming method or Hulu itself.
6. Try a wired connection or reset your router
Streaming over Wi-Fi can sometimes be inconsistent, especially during peak hours. If possible, use a wired Ethernet connection or restart your router to improve performance.

Long-term prevention tips
Once you have resolved the problem, you should take steps to prevent the problem from returning. Here are some preventive measures you can take:
- Keep all apps and devices up to date: Set your devices to update automatically where possible.
- Regularly clear the cache: Like cookies in a browser, video streaming apps collect background data that needs to be cleared occasionally.
- Avoid beta versions: If you are using a beta version of the operating system or testing firmware, Hulu’s app may not work properly with it.
- Use supported devices: Check Hulu’s website for a list of supported devices. Some older smart TVs and devices may no longer be fully compatible.
- Limit background activity: Multiple apps running simultaneously can eat up memory and network bandwidth, causing streaming errors.
When should you contact Hulu support?
If you’ve tried all the steps above and you’re still seeing error codes, it may be time to contact Hulu customer service. Make sure you take note of:
- The exact error code(s)
- Which device you use
- Your app and operating system versions
- Which solutions you have already tried
This information will help the support team diagnose your problem faster and provide a more accurate solution.
