To fix a Netflix error, copy the whole code and use the instructions for that exact code and device. Similar-looking numbers can mean different things. For example, D7121-5006 is about simultaneous streams; that does not tell you the meaning of D7121-1101.
Start with the matching entry below. If your code is not listed, search the Netflix Help Center using the full code, including any number in brackets. Avoid a factory reset as your first step.
Netflix error codes with confirmed starting points
| Exact code | What Netflix says | Where to start |
|---|---|---|
| NW-2-5 | The device took too long to connect to Netflix | Test the device’s internet connection and home network |
| D7121-5006 | The account has reached its simultaneous-stream limit | Stop playback on another device, then retry |
| UI-800-3 (205000) | Stored device data is stopping playback | Follow the sign-out and restart steps for that code |
| UI-800-3 (207006) | A digital-rights-management issue | Follow Netflix’s device-specific help; contact the manufacturer when directed |
| UI-800-3 (207003) | Typically a hardware issue | Use the manufacturer’s support steps rather than assuming it is Wi-Fi |
The extra numbers matter. Use Netflix’s pages for NW-2-5, D7121-5006, UI-800-3 (205000), UI-800-3 (207006), or UI-800-3 (207003) for the full procedure.
When Netflix will not connect
For a network error such as NW-2-5, try another internet app on the same device. If that also fails, focus on the device’s connection or router. A hotel, school, or other shared network may restrict streaming; ask the network owner rather than changing its settings.
If the problem is limited to Netflix, fully close and reopen it, then restart the device. Check the exact help page before changing DNS, VPN, or proxy settings. On your own home network, a normal router restart may help; a factory reset can erase your network setup and is a different action.
When Netflix fails in a browser
- Write down the full error code and browser name.
- Check that the browser and operating system are supported and updated.
- Try Netflix in another supported browser to narrow down the problem.
- If the exact help page points to cookies or stored data, clear Netflix’s site data rather than deleting every site’s data.
- If an extension affects playback, disable it temporarily and test again.
Clearing site data can sign you out. Make sure you know your login details first. Our guide to Edge extensions shows how to turn an extension off without removing everything.
What about D7121-1101, D7111-5702, or WEB-CG-2006?
We have not confirmed a public Netflix explanation for those exact codes in this review. Do not replace the final digits with a similar code and assume the same fix applies. Note whether the error appears during sign-in, video playback, or a Netflix game, then give Netflix support the complete message and device details.
A video error and a cloud-game error may involve different services. Repeatedly reinstalling the TV app or changing router settings can waste time when the code points elsewhere.
What to send support
Provide the exact code, device model, browser or app version, affected title, and whether another device works. Leave passwords and card details out. Once playback works, see how Netflix recommendations work if the next problem is finding something you want to watch.
Frequently asked questions
Do all UI-800-3 errors have the same fix?
No. Include any numbers in brackets and follow the matching device-specific help page. Some variants concern stored data, others hardware or playback authorization.
Should I factory-reset my TV first?
Start with the exact error instructions and simpler checks. A factory reset can remove apps, accounts and settings, and is not the first step for every error.
What does D7121-5006 mean?
Netflix says the account has reached its simultaneous-stream limit. Stop other active streams and check the account's plan if it keeps happening.
What details should I give Netflix support?
Provide the complete code, device model, app or browser version, and when it appears. Do not send passwords or payment details.
