Your show was playing fine, and now Hulu is stuck on a loading wheel, throwing an error code, or refusing to log you in. It can happen on a smart TV one night and your phone the next, which makes it hard to know where to even start.
The good news: most Hulu problems trace back to a short list of causes, and a handful of quick fixes clear up the majority of them. The fixes below are ordered quickest and most common first, so start at the top and only work your way down if the issue survives.
Each fix names the exact action and the menu path where it matters. Try one, then reopen Hulu and test before moving on.
Check Whether Hulu Itself Is Down
Before you touch your own setup, rule out an outage on Hulu's side. A server problem often shows up as codes like p-dev320, p-dev323, or a 500 error, and no amount of local troubleshooting will fix it.
Visit DownDetector.com or IsItDownRightNow, and search social media for "#huludown" or check @hulu_support for any outage acknowledgement. You can also reach Hulu support by phone at 1-888-265-6650.
While you are at it, confirm two things on your end: that other apps and sites stream normally on the same network, and that your Hulu subscription is active and not in a failed-payment or expired state. A lapsed payment can block both login and playback.
Restart the App, Then the Device, Then Your Network
This single sequence resolves more Hulu issues than any other, including buffering, freezing, and many load errors. Do all three steps in order.
- 1.Completely close the Hulu app on your device and reopen it.
- 2.Power cycle the streaming device. For smart TVs and streaming sticks, unplug it from power for about 1 minute, then plug it back in and let it fully reboot.
- 3.Restart your home network: unplug the modem and router for about 1 minute, plug them back in, and wait for a full reboot before retrying.
Clearing cache or reinstalling later is often not enough on its own, so do not skip the device restart.
Update the Hulu App and Your Device Software
An outdated app is directly linked to playback errors like 5003 and rununk13. Open your device's app or channel store, find Hulu, and install any available update.
Then update the device's own operating system or firmware, since stale system software can break playback too. Reopen Hulu once both are current.
Confirm Your Internet Meets Hulu's Speed Minimums
Slow or unstable internet is the most common cause of buffering and of errors like Error 3 and Error 5. Hulu's recommended minimums are 3.0 Mbps for the on-demand library, 8.0 Mbps for live streams, and 16 Mbps for 4K content.
Run a speed test to confirm you are at or above those numbers. Note that two figures circulate: the published 3.0 Mbps for standard definition versus the roughly 6 to 8 Mbps commonly cited for reliable HD, so treat 8 Mbps as a safe HD floor.
Live TV is the most fragile of Hulu's services because it has no buffer, which means a brief connection dip interrupts it instantly. To steady things, move closer to the router or switch to a wired Ethernet connection, and reduce other devices competing for bandwidth.
Turn Off Any VPN or Proxy
If you see Error 16, the cause is region detection, not a broken app. Hulu thinks your connection is outside the United States, and even U.S. subscribers trigger it when a VPN or proxy makes their connection look foreign.
Disable the VPN or proxy service entirely, then reload Hulu. Reinstalling the app will not help here; turning off the VPN is the actual fix.
Clear the Cache on Your Device
A corrupted cache causes crashes, frozen playback, and load errors. The method depends entirely on your device.
On Android, open Settings, then Apps, find Hulu, tap Storage & Cache, and tap Clear Cache. If the problem persists you can tap Clear Data, but be warned: that logs you out and resets app settings.
On Fire TV, go to Settings > Applications > Manage Installed Applications, select Hulu, and choose Clear Cache. You can also choose Force Stop on the same screen to fully close the app.
iOS gives no per-app clear-cache button at all. Your options are to open Settings > General > iPhone Storage, select Hulu, and tap Offload App to clear it while keeping data, or to delete and reinstall the app outright.
Roku and Samsung TVs also lack a direct cache control. On Roku, from the Home screen press Home 5 times, then Up, then Fast Forward twice, and wait 20 to 30 seconds. (This is a community-documented shortcut and may not work on every Roku OS version.) On Samsung, the practical equivalent is a 60-second power-unplug soft reboot.
Clear Your Browser Cache or Switch Browsers
If you watch on hulu.com in a desktop browser, a stale cache or cookies can cause buffering and the rununk13 error. Clear your browser's cache and cookies, then reload the page.
For a 500-type server error, refresh the page or switch to a different browser. For protected-content errors such as 2203, 3307, 3321, 3322, 3336, 3343, or 0326, update or switch to a different, supported browser and refresh.
Reinstall the Hulu App
If updating and clearing cache did not work, remove Hulu completely and reinstall it. This rebuilds the app from scratch and clears any corrupted files left behind.
- Fire TV: Settings > Applications > Manage Installed Applications > highlight Hulu > Uninstall, wait a few minutes, then reinstall from the Appstore.
- Roku: press Home, highlight the Hulu channel, press the Star (*) button, choose Remove channel and confirm, then reinstall from the Channel Store.
- iOS: press and hold the icon, tap Remove App, confirm Delete App, then reinstall from the App Store.
- Apple TV: highlight Hulu, hold the touch surface until icons jiggle, press Play/Pause and choose Delete, then redownload.
- Samsung: highlight Hulu, press Down, choose Remove, then re-add from the app store.
After reinstalling, restart the device once more before testing.
Remove and Re-add the Device on Your Account
Error 400 looks like a login failure but is fixed differently: by removing and re-adding the device, not by resetting your password.
- 1.Go to hulu.com/welcome on a computer and sign in.
- 2.Open Account settings, then select Manage Devices.
- 3.Find the problem device in the list and select Remove.
- 4.Reinstall the Hulu app on that device and sign in again to reactivate it.
This is also the documented fix for console errors p-dev320 and p-dev323 on Xbox, PlayStation, and similar players.
Fix Login, Password, and Lockout Problems
If you cannot sign in, first confirm you are using the correct email and password with nothing misspelled. If you are unsure, use the "Forgot password" reset link and follow the email to set a new one.
If the reset email never arrives, check your spam folder, confirm no filters are blocking it, and verify you are using the email tied to the account. If login still fails, double-check that the subscription has not lapsed on payment.
When a smart TV or streaming device rejects correct credentials, delete and reinstall the Hulu app to clear the glitch. If you are fully locked out, use Hulu's locked-out support flow or contact support directly.
Fix Audio, Captions, and HDMI Handshake Errors
For no sound or surround issues, switch to a different title and back to trigger a soft reset. If that fails, open your TV or soundbar audio settings and change the output from surround or Bitstream to PCM or Stereo.
HDCP and protected-content codes (2203, 3307, 3321, 3322, 3336, 3343, 0326) are hardware-handshake failures, not app problems. Reseat or replace the HDMI cable, try a different port or display, and avoid HDMI splitters; verify cables match the "in" and "out" arrows on your devices.
If captions show the wrong language, check the caption setting in both your TV's and the app's settings, then relaunch Hulu. If captions are missing entirely for a title, report it to Hulu's captions feedback address.
Frequently Asked Questions
Why does Hulu say "too many videos" or hit a stream limit?
Hulu's base plan allows only 2 simultaneous streams. This message is by design, not a bug, so the only options are to close one of the active streams or upgrade your plan.
How do I clear the Hulu cache on iPhone? There is no Clear Cache button.
Correct, iOS has no per-app clear-cache option. The real equivalents are Offload App via Settings > General > iPhone Storage, which keeps your data, or deleting and reinstalling the app, which removes everything.
What internet speed do I actually need for Hulu?
Hulu lists 3.0 Mbps for the on-demand library, 8.0 Mbps for live streams, and 16 Mbps for 4K. Because Live TV has no buffer and is sensitive to dips, treat 8 Mbps as a safe HD floor and 16 Mbps for anything 4K.
What does Error 16 mean and how do I fix it?
Error 16 means Hulu thinks you are outside the United States, almost always because a VPN or proxy is active. Turn the VPN or proxy off and reload; reinstalling the app will not resolve it.
Why does clearing the cache not fix my problem on its own?
Clearing cache alone is frequently insufficient. After clearing cache or reinstalling, restart the device as well, since a fresh reboot is often what finally clears the error.
Error 400 looks like a login issue, so why not reset my password?
Error 400 is fixed by removing and re-adding the device at hulu.com > Account > Manage Devices, then reinstalling the app. A password reset addresses a different problem and will not clear this code.
