Most "Hulu not downloading" issues aren't just random glitches. Whether it's the stubborn Hulu download error code 16911 or the error code 6, these bugs usually stem from outdated DRM (Digital Rights Management) protocols or a "hidden" account limit that Hulu doesn't clearly advertise.
In this guide, I'll explain the true meaning of various Hulu error codes. And I'll skip the generic "restart your phone" advice and dive into the real fixes that actually worked for the Reddit community and me in 2026. Read on to troubleshoot your Hulu downloads not working problem.
Quick Guide:
Common Hulu Download Errors: Why and How I Fixed Them
When Hulu's download feature hits a wall, it usually throws a specific number at you. Here's a breakdown of the most frequent Hulu error code I've encountered recently.
Hulu Error Code 500 and Code 6
While Hulu officially labels Error 500 as an "Internal Server Error," my testing shows it’s often triggered by a handshake failure between your device and Hulu's DRM server. Normally, it has nothing to do with your app or device. It is more about something bad at the Hulu end.
🔧 To fix Hulu error code 500: If you're on a laptop, check your browser extensions. According to recent user reports on Quora, privacy-focused extensions like DuckDuckGo or aggressive Ad-blockers often intercept the download request, triggering a 500 or 6 error. Disable them temporarily, and you'll likely see the download resume.
If the problem persists or you're using a mobile app, the only thing you can do is wait until the Hulu server gets fixed.
Hulu Download Error Code 16911 & 16657
These codes are the bane of iOS and Android users. Error 16911 typically means the "Core Media" player on your device has lost its license authorization, while error 16657 is related to DRM (Digital Rights Management) restrictions.
🔧 To fix Hulu code 16911 or 16657: Don't just restart the app. Toggling "Background App Refresh" OFF in your device settings can actually help. Because when Hulu tries to "verify" your downloads in the background over a shaky Wi-Fi, it often fails and "locks" the file.
By turning off background refresh, you prevent the app from accidentally invalidating your offline licenses.
Hulu Download Error Code 28
This error often occurs when your storage is technically sufficient, but the "session" has timed out.
🔧 To fix Hulu code 28: Before reinstalling the app, check if you've reached the 25-video limit. Hulu allows 25 downloads per account, not per device. If your family members have already filled up the quota on their iPads, you will get Error 28 on your phone without a clear explanation.

Hulu Download Error Code 3 and Code 5
This error also results when the Hulu app cannot connect to the server. But this time, Hulu itself is not a culprit. It is typically because you have a weak internet connection or the app itself is outdated.
🔧 To fix Hulu code 28:
- Restart your Hulu app.
- Check your internet connection. You can even consider upgrading to a higher plan or changing your ISP
- Check if you have an update pending for the Hulu app.
- You can also check if switching to a wired connection helps.
Hulu Download Error Code 9
It will come up when using Hulu on a smart TV. In most cases, the error code indicates that there is a connectivity issue or a problem with the authentication of the device and your account.
🔧 To fix Hulu code 9:
- Uninstall and reinstall the Hulu app
- Log out of your Hulu account and log back in
- Restart your modem or router to rule out the internet connectivity issues.
Quick Tweaks When Hulu Is Not Downloading at All
Sometimes, you won't even get a specific Hulu download error code at all. The app simply refuses to start the download or gets stuck at 0%. If your Hulu not downloading issue persists, here are the two most effective checks I perform before giving up:
Common Fix 1
Check for IPv6 / Network Roaming Drops
Hulu's security is notoriously strict about IP address stability. If your phone switches between a 5GHz and 2.4GHz Wi-Fi band, or if your router is handing out unstable IPv6 addresses, Hulu will halt the download to prevent account sharing.
I highly recommend forcing your phone to cellular data temporarily or turning off Wi-Fi assist to keep the connection unified.
Common Fix 2
Clear the "Ghost" Storage
A common bug in the 2026 version of the Hulu app is that it misreads your available storage. Even if your phone says you have 50GB free, the app's cache might think it's full.
- On Android, force stop the app and clear the cache (not data).
- On iOS, you unfortunately have to offload and reinstall the app to flush this ghost data.
[Alternative] Download Hulu Videos as MP4 to Avoid Server Error
Fixing Hulu error codes can be a huge concern, and it can become quite tiring. Sometimes, the problem lies in the Hulu server, and the only thing we can do is wait. Don't worry. There is another alternative to fix such an inevitable Hulu error code: use a tool to download Hulu videos as MP4 files.
Software like KeepStreams for Hulu is designed for this. Instead of renting the file temporarily within an app, KeepStreams allows you to download Hulu videos directly to your PC or Mac as standard MP4 or MKV files, in high quality up to Full HD 1080p or 4K.
This method eliminates the risk of encountering a Hulu download error code while entirely offline, because the video is saved locally on your hard drive, DRM-free.
Here's how to use KeepStreams to download Hulu videos:
Step1
Install KeepStreams on your computer
Step2
Choose Hulu from the VIP Services list
Sign in to the Hulu streaming service using your account. KeepStreams can't directly remove DRM, which is illegal and risky. It requires your access to download Hulu videos.
Step3
Search and play the video you want to download
Search for and play the video that you want to download. Wait for analysis, and a settings window will follow up soon. Choose your preferred video resolution, audio tracks, and subtitle preferences.
Step4
Download the video as MP4 files
Click on Download Now to begin downloading the video right away. You can check the download progress from within the app. Once done, the videos will be saved in a compatible MP4 format in the local folder.

FAQs
Q1. Why do my Hulu downloads disappear when I go offline?
A1. This is a known bug. When you switch to airplane mode or lose Wi-Fi, the Hulu app may try to "ping" its servers in the background to verify your DRM licenses. When it fails, it hides or deletes the downloads. To prevent this, turn off "Background App Refresh" for Hulu in your phone's settings before you go offline.
Q2. Why does Hulu say I reached my download limit when I have phone storage?
A2. Storage space isn't the issue here. Hulu enforces a strict limit of 25 downloaded videos per account, spread across a maximum of 5 supported devices. If your family members share your account and have downloaded 25 episodes of a cartoon on their tablets, you won't be able to download anything on your phone until they delete theirs.
Q3. How long do Hulu downloads actually last?
A3. Unwatched downloads remain on your device for up to 30 days. However, the clock ticks faster once you start watching: the moment you press play, you only have 48 hours to finish the video before the download automatically expires and requires an internet connection to renew.
Conclusion
Hulu download error codes, such as error code 500, 6, or 16911, might pop up at any time. Hope this post can help you fix them much faster than simply restarting your router. Remember to check your family's overall download limit, and turn off background app refresh if your files keep disappearing.
If the app continues to fail you, consider exporting your shows locally via tools like KeepStreams for Hulu. Although you do need a computer to use it initially (you can transfer the MP4 files to your phone later), it's a reliable workaround if you are constantly battling app crashes.
