Samsung TV Apple TV app sign-in fails: 'Something went wrong
Hi. I have been unable to play my Apple TV app on my Samsung 43" UHD for about a week. It works on all other devices. I have done half a day of troubleshooting and still no success. If anyone has any experience of this problem, I'd like to hear about it!
Here's my troubleshooting log.
TV Model: Samsung UE43DU7100KXXU
Firmware: T-KSU2EDDEUC-1301.0
Issue: Apple TV app loads to Home screen, but pressing Sign In always returns “Something went wrong”.
Occurs on multiple networks.
Network-Level Troubleshooting
- Tested on home Wi-Fi (strong signal, ~150 Mbps).
- Tested with DNS changed to Google (8.8.8.8) and Cloudflare (1.1.1.1).
- Tested on iPhone personal hotspot — identical failure.
- Restarted router and confirmed no filtering or parental controls active.
- Confirmed other apps (Netflix etc.) work normally.
Apple ID / Account Troubleshooting
- Removed TV and other devices from Apple ID device list.
- Waited for Stolen Device Protection security delay to expire.
- Confirmed Apple ID devices list loads normally.
- Tested Apple TV login on other Apple devices — all working.
- Apple ID sign-in works on every device except the Samsung TV.
Samsung TV App / Smart Hub Troubleshooting
- Deleted and reinstalled Apple TV app multiple times.
- Performed several hard reboots (holding Power for 5–10 seconds).
- Power-cycled TV at wall (unplugged for 60 seconds).
- Performed Smart Hub Reset.
- Attempted to access Smart Hub region reset (not available on this firmware).
- Disabled autorun settings via Start Screen Options.
- Tried all Apple TV app sign-in methods (QR code never appears).
TV-Level Troubleshooting
- Performed a full Factory Reset of the TV.
- Completed fresh setup (Wi-Fi + Samsung account).
- Installed Apple TV app before any others.
- Re-tested on both Wi-Fi and iPhone hotspot after factory reset — identical failure.
- Confirmed No firmware updates available — TV stuck on 1301.0.
Observed Behaviour
- Apple TV app launches with long spinner (~1 minute).
- Home screen loads normally (content thumbnails appear).
- Pressing Sign In immediately returns: “Something went wrong.”
- No QR code or password prompt ever appears.
- Behaviour unchanged across all networks and after full reset.
Conclusion Based on Troubleshooting
- Issue is not network-related (fails on multiple networks).
- Issue is not Apple ID-related (other devices sign in; device list normal).
- Issue is not app-cache or Smart Hub related (factory reset + reinstalls did not resolve it).
