When Prime Video won’t work on your Roku, start by restarting your device through Settings > System > System Restart or unplugging it for 30 seconds. If that doesn’t help, update both your Roku system and the Prime Video app, then remove and reinstall the app to clear corrupted data. Check that your internet speed meets minimum requirements — 5 Mbps for HD or 18 Mbps for 4K. You should also verify your Amazon account status and subscription validity to rule out payment issues blocking access.
Quick Guide
- Restart your Roku device via Settings > System > System Restart, or unplug for 30 seconds to clear temporary cache issues.
- Update both Roku system software and the Prime Video app via Settings > System > Software update and the app’s own update check.
- Remove and reinstall Prime Video: press * on the app, select Remove Channel, then reinstall from Streaming Channels.
- Confirm your network meets minimum requirements — 5 Mbps for HD, 18 Mbps for 4K — with 30/36 Mbps recommended to avoid buffering.
- Verify your Amazon Prime membership status and payment method under “Your Prime Membership.”

Common Reasons Prime Video Stops Working on Roku
Issues usually fall into one of five categories: app installation problems, streaming performance, network connectivity, device hardware limitations, or account access. Each has distinct symptoms — from a complete loading failure to intermittent buffering — and calls for a different fix. A simple power cycle (unplugging for 10-15 minutes and reconnecting) resolves a surprising share of these regardless of category, so it’s worth trying first before diagnosing further.
Quick Restart Solutions
Before anything more involved, restart via Settings > System > System Restart, or unplug for 30 seconds and reconnect. For persistent issues, restart your router and modem first, then reboot your Roku. This clears temporary cache and refreshes the system. Also check your power supply and HDMI connections are secure — try the original power adapter or a different HDMI port if problems continue, and see our guide on what to do if Roku gets stuck on the bouncing logo if a restart doesn’t complete normally.

Update Your Roku System and Prime Video App
Go to Settings > System > Software update > Check now for the Roku system. For the Prime Video app specifically, press the star button on your remote, select the app, then choose “Check for updates.” Your Roku also checks for updates automatically every 24-36 hours when connected to the internet.
Reinstall the Prime Video App
If updating didn’t fix it, a fresh install often clears persistent problems. From the Home screen, highlight Prime Video, press the asterisk (*) button, select “Remove Channel,” and confirm. Then open “Streaming Channels,” search for Prime Video, reinstall it, and sign in with your Amazon credentials again.

Check Your Internet Connection Speed and Stability
Many playback issues come down to insufficient speed rather than an app or device problem. Standard Definition needs 1 Mbps minimum, HD needs 5 Mbps, and 4K needs 18 Mbps — but those are bare minimums, not comfortable targets. For smooth playback without buffering, aim for 30 Mbps for HD and 36 Mbps for 4K. Run a speed test during peak evening hours specifically, since that’s when a connection is most likely to fall short of what it tests at other times. Restarting your modem and router often resolves intermittent speed or stability problems too.
Optimize Your Network Settings for Streaming
Position your router centrally, away from walls and metal objects. Switch to the 5GHz band for faster speeds with less interference. Keep your router’s firmware updated, and limit how many other devices are active during a streaming session to maximize the bandwidth available to your Roku.

Verify Your Amazon Account and Subscription Status
Before troubleshooting device settings further, confirm your Amazon account is actually in good standing. Sign in to Amazon.com, go to “Your Prime Membership” under “Accounts & Lists,” and check your subscription status, expiration date, and payment method for any pending issues or security alerts. Worth knowing while you’re there: see our guide on what Prime membership actually includes in Australia if you’re not sure everything you’re paying for is even active.
Clear Cache and Reset App Data
Cached data can build up over time and cause freezing, endless buffering, or a failure to launch at all. Clear your Roku’s system cache by pressing Home five times, Up once, Rewind twice, then Fast Forward twice — your device restarts automatically. Alternatively, uninstall Prime Video from the home menu and reinstall from the Roku Channel Store to reset app-specific data.

Alternative Ways to Watch Prime Video
If Roku troubleshooting hasn’t worked, you’ve got other options. Connect a computer directly via HDMI and stream through a browser at amazon.com/video. Use Chrome’s Cast feature from a computer, or the Cast icon from the mobile app. Fire TV and Apple TV also both support Prime Video natively if you want to rule out Roku specifically as the problem.
Wrapping Up
Getting Prime Video working on Roku rarely needs deep technical knowledge — start with the simplest fixes (restart, update, reinstall) before moving to network optimization or account checks. If you’re dealing with playback issues on other devices too, our guides to low Roku TV volume and switching Roku TV inputs cover related ground. If problems persist after everything here, contact Amazon or Roku support directly for device-specific help.
