Errors
Hulu not loading or constantly buffering is a frustrating experience, especially when you are in the middle of a show. Streaming failures on Hulu can manifest as a blank screen, endless spinning loader, frozen video with audio continuing, or complete playback errors with error codes. These problems occur on every device — Smart TVs, Roku, Amazon Fire Stick, Apple TV, gaming consoles, phones, tablets, and web browsers.
The root cause is almost always related to internet connectivity, app cache, or device compatibility. Hulu requires a minimum download speed of 3 Mbps for standard streaming, 8 Mbps for live TV, and 16 Mbps for 4K content. If your internet speed drops below these thresholds, buffering or loading failures occur. However, speed is not the only factor — Wi-Fi interference, DNS issues, outdated apps, and overloaded devices can all cause identical symptoms.
This guide provides targeted fixes organized by device type, starting with universal solutions that work on all platforms and then moving to device-specific troubleshooting steps.
Close the Hulu app completely, restart your streaming device, and restart your router by unplugging it for 30 seconds. Reopen Hulu. This three-step restart resolves the majority of Hulu loading and buffering issues by clearing temporary data and refreshing the network connection.
Common symptoms: Black screen / Spinning loader / "We're having trouble playing this" / Buffering every few seconds / App crash on launch / Error code RUNUNK13Method 1: Universal Fixes for All Devices
These steps apply regardless of which device you use to watch Hulu. Start here before moving to device-specific methods.
Check Hulu Server Status
Before troubleshooting your equipment, verify Hulu's servers are operational. Visit downdetector.com/status/hulu or check Hulu's official Twitter/X account (@haborhelp) for outage reports. If thousands of users are reporting issues, the problem is on Hulu's side and you need to wait for them to fix it.
Restart Your Router and Modem
Unplug your router and modem (if separate) from power. Wait 30 seconds. Plug the modem back in first and wait for all lights to stabilize (usually 1-2 minutes). Then plug the router back in. Wait another 1-2 minutes for Wi-Fi to come back up. This clears the router's cache and can resolve DNS issues that block streaming services.
Test Your Internet Speed
Run a speed test at fast.com (Netflix's speed test) or speedtest.net from the same device you use for Hulu. You need at least 3 Mbps for SD streaming, 8 Mbps for HD, and 16 Mbps for 4K. If your speed is lower than expected, try moving closer to the router, connecting via Ethernet instead of Wi-Fi, or disconnecting other devices that may be using bandwidth.
Close Other Apps and Devices
Streaming on multiple devices simultaneously consumes bandwidth and may exceed your plan's capacity. Close other streaming apps, pause large downloads, and disconnect devices you are not using. On the device running Hulu, close all other apps running in the background to free up processing power and memory.
Tip: If Hulu loads fine on one device but not another, the problem is device-specific (app cache, outdated software, or hardware limitations). If Hulu fails on all devices, the issue is your internet connection or Hulu's servers.
Method 2: Fix Hulu on Smart TVs (Samsung, LG, Vizio)
Smart TVs often have limited memory and processing power, making them more prone to app loading issues than phones or computers.
Force Close and Reopen Hulu
On Samsung: press and hold the Back button until you return to the home screen. On LG: press the Home button, highlight the Hulu app, press and hold the select button, choose Close. On Vizio: press the Home button and relaunch Hulu. Simply pressing the Home button often only minimizes the app — you need to fully close it.
Clear Hulu App Cache
On Samsung: go to Settings > Apps > Hulu > Clear cache and Clear data. On LG: uninstall and reinstall the Hulu app (LG does not have a separate cache clearing option). On Vizio: perform a soft power cycle by unplugging the TV for 60 seconds. You will need to sign in to Hulu again after clearing data.
Update the Hulu App and TV Firmware
Open your TV's app store and check for a Hulu update. Also check for a TV firmware update in Settings > System > Software Update. Outdated app versions and firmware can cause compatibility issues with Hulu's streaming servers.
Cold Boot the TV
Unplug the TV from the wall outlet (not just the power strip). Press and hold the power button on the TV itself (not the remote) for 10 seconds to discharge residual power. Wait 60 seconds, then plug it back in. This full cold boot clears the TV's memory more thoroughly than a remote-control power off.
Method 3: Fix Hulu on Roku, Fire Stick, and Apple TV
Streaming sticks and boxes are dedicated devices but can still experience app and connectivity issues.
Restart the Streaming Device
Roku: Go to Settings > System > System restart. Fire Stick: Go to Settings > My Fire TV > Restart. Apple TV: Go to Settings > System > Restart. Alternatively, unplug the device for 30 seconds and plug it back in.
Reinstall the Hulu App
Roku: Highlight the Hulu channel, press the Star button, select Remove channel. Then go to Streaming Channels > Search > Hulu and re-add it. Fire Stick: Go to Settings > Applications > Manage Installed Applications > Hulu > Uninstall, then reinstall from the Appstore. Apple TV: Highlight the Hulu app, press and hold the touchpad, select Delete, then reinstall from the App Store.
Check for Device Updates
Outdated firmware on streaming devices can cause app incompatibilities. Roku: Settings > System > System update. Fire Stick: Settings > My Fire TV > About > Check for Updates. Apple TV: Settings > System > Software Updates > Update Software.
Method 4: Fix Hulu on Web Browsers
Browser-specific issues like extensions, cached data, and outdated browsers can prevent Hulu from loading.
Clear Browser Cache and Cookies
In Chrome: press Ctrl + Shift + Delete, select Cached images and files and Cookies, set the time range to All time, and click Clear data. In Firefox: press Ctrl + Shift + Delete, select Everything, check Cache and Cookies, and click Clear Now. Close and reopen the browser, then try Hulu again.
Disable Browser Extensions
Ad blockers, VPN extensions, and privacy tools commonly interfere with streaming services. Disable all extensions temporarily by going to chrome://extensions (Chrome) or about:addons (Firefox) and toggling them off. If Hulu works after disabling extensions, re-enable them one by one to find the culprit.
Try a Different Browser or Incognito Mode
Open Hulu in an incognito/private window (Ctrl + Shift + N in Chrome, Ctrl + Shift + P in Firefox). Incognito mode disables all extensions and uses a clean session. If Hulu works in incognito, the issue is with your browser profile. If it fails in all browsers, the problem is network-related.
Warning: Using a VPN while streaming Hulu will cause loading failures. Hulu blocks most VPN IP addresses to enforce geographic licensing restrictions. Disable your VPN before opening Hulu. If you use a VPN for privacy, configure split tunneling to exclude Hulu from the VPN tunnel.
Why Does This Problem Happen?
Hulu loading and buffering issues stem from several interconnected causes:
- Wi-Fi congestion: The 2.4 GHz Wi-Fi band is shared with many household devices (microwaves, baby monitors, Bluetooth devices) and neighboring networks. Switching to the 5 GHz band provides a cleaner, faster connection for streaming.
- ISP throttling: Some internet service providers intentionally slow down streaming traffic during peak hours. If Hulu buffers at certain times but works fine at others, your ISP may be throttling your connection. A VPN can sometimes bypass throttling, but Hulu may block the VPN.
- Outdated app version: Hulu regularly updates its app with new DRM requirements, codec support, and bug fixes. Running an outdated version can cause playback failures even if your internet connection is fine.
- Device memory pressure: Smart TVs and older streaming devices have limited RAM. Running multiple apps or having a full app cache leaves insufficient memory for Hulu to buffer and decode video properly.
- DNS resolution issues: If your ISP's DNS servers are slow or experiencing issues, Hulu's content delivery network (CDN) requests may fail or resolve to suboptimal servers, causing buffering.
Frequently Asked Questions
Different streaming services use different content delivery networks (CDNs) and servers. Your ISP may have better peering agreements with Netflix's CDN than with Hulu's. Additionally, Netflix has more aggressive adaptive bitrate algorithms that downgrade quality faster to avoid buffering, while Hulu may try to maintain higher quality longer, resulting in buffering instead of quality reduction.
Hulu recommends 3 Mbps for the standard Hulu library, 8 Mbps for live TV, and 16 Mbps for 4K content. These are per-stream requirements — if two people are watching simultaneously, you need double the bandwidth. For reliable streaming, having 25+ Mbps gives you comfortable headroom for multiple devices.
A black screen usually indicates a DRM (digital rights management) or HDCP issue. Check that your HDMI cable supports HDCP 2.2 for protected content. Try a different HDMI port on your TV. On computers, disable hardware acceleration in your browser settings (Chrome: Settings > System > Use hardware acceleration). Update your graphics drivers to the latest version.
App crashes are usually caused by insufficient memory, corrupted app data, or firmware bugs. Clear the Hulu app cache and data in your TV's settings. If crashes continue, uninstall and reinstall the app. Check if your TV model is still supported by Hulu — very old Smart TVs may no longer receive app updates and eventually lose compatibility.
The basic Hulu plan allows two simultaneous streams. Hulu + Live TV plans also allow two screens by default. If you need more, the Unlimited Screens add-on allows unlimited streaming on your home network plus three streams on mobile devices. Exceeding your screen limit results in a playback error on the additional device.
Error RUNUNK13 is a playback failure that typically occurs on Smart TVs and streaming devices. Clear the Hulu app cache, restart the device, and check for app updates. If the error persists, uninstall and reinstall the Hulu app. On Samsung TVs, a cold boot (unplug for 60 seconds) often resolves this specific error.
No. Hulu actively detects ad blockers and will either show you a blank screen during ad breaks or prevent playback entirely. Disable your ad blocker for hulu.com. If you want an ad-free experience, subscribe to the Hulu (No Ads) plan, which eliminates most commercial breaks from on-demand content.
Hulu is only available in the United States and U.S. military bases overseas. If you see this message while in the U.S., Hulu may be detecting a VPN or proxy. Disable any VPN or proxy service. If you are using a mobile hotspot, the hotspot's IP address may be registered to a different region — try switching to Wi-Fi or a different network.
In the Hulu app, go to your profile icon > Settings > Video Quality (or Data Usage). Select a lower quality option like "Data Saver" or "Medium." On web browsers, Hulu automatically adjusts quality based on available bandwidth — you cannot manually set it. Lowering the quality reduces bandwidth requirements and eliminates buffering on slower connections.
Ethernet is always more reliable than Wi-Fi for streaming. If your streaming device has an Ethernet port (or supports a USB-to-Ethernet adapter), use a wired connection. Ethernet eliminates Wi-Fi interference, provides consistent bandwidth, and reduces latency. If Ethernet is not feasible, use the 5 GHz Wi-Fi band and position your device as close to the router as possible.
