Netflix error code UI3012: Have you ever settled in to binge your favorite Netflix show only to be greeted with a frustrating message that says:
“Whoops, something went wrong… Unexpected Error. There was an unexpected error. Please reload the page and try again.”
If the error code UI3012 pops up, you’re not alone. It’s a common Netflix issue that typically points to a network connectivity problem, meaning your device can’t communicate properly with Netflix servers.
What is Netflix Error Code UI3012?
Netflix error code UI3012 usually occurs on web browsers (like Chrome or Safari) or streaming devices when there’s a network disruption, poor Wi-Fi signal, or custom internet settings interfering with Netflix.

Common causes include:
- Weak or unstable internet connection
- VPN or proxy interference
- Public networks with streaming restrictions
- Faulty modem/router settings
Step-by-Step Fix for Error UI3012
1. Reload the Netflix Page
Sounds simple, but sometimes reloading the page refreshes the connection. Press Ctrl + R (Windows) or Cmd + R (Mac) to refresh.
2. Restart Your Network Devices
Turn everything off and reboot your network from scratch:
- Power off your computer or streaming device.
- Unplug your modem and router for 30 seconds.
- Plug the modem back in and wait for it to fully restart.
- Then plug in your router (if separate).
- Power your device back on and try Netflix again.
3. Use a Wired Ethernet Connection
If you’re on Wi-Fi, switch to an Ethernet cable. Wired connections are faster and more reliable, reducing the chance of interruptions.
4. Improve Your Wi-Fi Signal
- Move your router and streaming device closer.
- Avoid obstacles like walls, microwaves, and cordless phones.
- Place the router higher (on a desk or shelf).
5. Disable VPN, Proxy, or Custom DNS
Custom network settings or VPNs can block Netflix.
- Turn off any VPN or proxy service.
- Restore your DNS settings to default (“Auto” mode).
- If you’re unsure, contact your device’s manufacturer or your ISP.
6. Try a Different Browser or Device
- Use another browser (Chrome, Firefox, Edge).
- Try watching on the Netflix app instead of the browser.
- Make sure your browser or app is updated to the latest version.
7. Check Netflix Server Status
Sometimes, the issue is on Netflix’s end. Visit Netflix’s server status or search “Is Netflix down?” online to confirm.
8. Connect to a Different Network
If you’re using a public network (e.g., in a café, hotel, or school), the administrator may have blocked streaming services. Try a personal network or mobile hotspot.
Still Not Working? Contact Your Internet Service Provider
If none of the above solutions help:
- Test your internet speed at fast.com (Netflix’s own tool).
- Call your ISP and let them know:
- If the issue is on one device or all devices.
- Whether you’re on Wi-Fi or Ethernet.
- Your average internet speed.
Your ISP can check for outages, reset your connection, or assist with modem/router issues.
Final Thoughts
Netflix error code UI3012 might be annoying, but it’s fixable with the right steps. Most often, a quick network reset or disabling a VPN does the trick. If you’re still stuck, switching networks or getting help from your ISP will usually get you back to streaming without interruptions.
