Apple Apple TV HD Error Code 42

If you're seeing Apple Apple TV HD error code 42 on your screen, you're dealing with a network connectivity or content authorization issue that prevents streaming.

What Causes Error Code 42 on Apple TV HD?

Error code 42 generally signals one of three underlying problems: network instability blocking server communication, outdated software causing authentication failures, or corrupted app data interfering with content playback. Understanding the root cause helps you apply the most effective fix without wasting time on unnecessary steps.

How to Fix Apple Apple TV HD Error Code 42

Work through these solutions in order. Test your Apple TV HD after each step to see if the error has cleared.

Restart Your Apple TV HD: Unplug your Apple TV HD from power, wait 10 seconds, then plug it back in. This clears temporary memory glitches that commonly trigger error code 42. Avoid simply putting the device to sleep—a full power cycle is essential.

Check Your Network Connection: Go to Settings > Network on your Apple TV HD and verify you're connected. Run a speed test from another device on the same network. Apple recommends at least 8 Mbps for HD streaming. If your connection is weak, move your router closer or switch to a 5 GHz Wi-Fi band.

Restart Your Network Equipment: Power cycle your modem and router by unplugging both for 30 seconds, then plug in the modem first followed by your router. Wait for all lights to stabilize before reconnecting your Apple TV HD. This resolves ISP-side authentication blocks that can cause Apple Apple TV HD error code 42.

Update tvOS Software: Navigate to Settings > System > Software Updates > Update Software. Install any available updates. Apple frequently patches connectivity bugs that produce error 42, and running outdated tvOS is a common trigger for this specific issue.

Sign Out and Back Into Your Apple ID: Go to Settings > Users and Accounts > [Your Name] > Sign Out. After signing out, restart your device, then sign back in with your Apple ID credentials. This refreshes your content licenses and can clear authentication-related instances of error code 42.

Reset Network Settings: If the error persists, go to Settings > General > Reset > Reset Network Settings. You'll need to re-enter your Wi-Fi password. This eliminates corrupted network configurations that may be blocking Apple's servers despite appearing connected.

Warning: Do not perform a full factory reset as your first troubleshooting step. Resetting all content and settings erases your apps, accounts, and preferences. Only use this option if all other steps fail to resolve Apple Apple TV HD error code 42, and ensure you know your Apple ID password before proceeding.

Frequently Asked Questions

Does error code 42 mean my Apple TV HD is defective?

No, error code 42 is almost always a software or network issue, not a hardware failure. Apple TV HD units rarely fail in ways that produce this specific error. If you've exhausted all troubleshooting steps, contact Apple Support before assuming hardware replacement is needed.

Can a VPN or DNS service cause Apple Apple TV HD error code 42?

Yes. VPNs, smart DNS services, and custom DNS configurations frequently trigger this error by routing your traffic through servers that Apple's content delivery network rejects. Disable any VPN or DNS changes, restart your Apple TV HD, and test again.

Why does error 42 only appear with certain apps or shows?

This pattern indicates a DRM or regional licensing problem rather than a general network failure. The content may require re-authentication, or your Apple ID region may not match your physical location. Signing out and back into your Apple ID typically resolves app-specific occurrences of Apple Apple TV HD error code 42.
