Netflix T1-H1 errors indicate the video streaming platform denied the connection request sent by your Windows 10 computer.
In other words, Netflix has detected you’re using specialized software to bypass its region restrictions. Examples of such tools include VPN software, proxy tools, unblocker programs, or software that hide your IP address.
Geographic Restrictions on Netflix
Netflix has a diverse content library that may vary depending on the region you’re currently located in. These geographic restrictions are mainly due to licensing agreements.
The platform uses your IP address to identify your current region and display the content available in the respective region or country. Every country has its own Netflix content library.
Some users may try to hide their real location and replace their real IP with a software-generated IP so as to stream movies and TV shows that otherwise are not available in their library.
When Netflix detects such attempts, it blocks the connection and throws T1-H1 errors to the screen. You may get the same error if you’re using a VPN simply for privacy purposes.
How to Fix Netflix T1-H1 Errors
Disable your VPN
If you’re using a VPN or IP hiding software on your computer for privacy reasons only, you may want to disable it while watching Netflix.
Netflix can’t tell what’s your real intention when using a VPN. You may simply want to take control of your personal data and prevent third-parties from accessing it.
You may have no intention to bypass regional or geographic restrictions. But Netflix doesn’t know that. And so the platform assumes you’re using a VPN to bypass its geographic restrictions and blocks your IP.
If you’re not using a VPN, and you know the content you’re trying to stream is indeed available in your region, pursue the following troubleshooting steps.
Restart your computer and modem
Restarting your computer and modem will delete any temporary files that might be interfering with your Netflix session.
To rule out network connectivity issues, go ahead and restart your modem as well. Or you can take this one step further and unplug the power cord to completely power cycle the device.
Use a cable connection
Streaming video content requires quite a lot of bandwidth. To make sure your connection can support this task, use a cable connection if that’s possible. Another thing you can do is to disconnect all the other devices using the connection.
Use a different browser
If the error persists despite restarting your computer and modem, and switching to a cable connection, try using a different browser.
Don’t forget to clear your browser cache as well. Click on your browser menu, select History, locate the Clear browsing data option, and click on it.
Close the browser, launch it again, and check if you can connect to Netflix now.
Reset your Netflix app
If you’re using the Netflix desktop app, try resetting it.
- Go to Apps & Features
- Scroll down to Netflix
- Select the app and click on Advanced options
- Click on the Reset button
- Check if the issue is gone
- If it persists, go back to Apps & Features → Netflix
- This time, click on the Uninstall button
- Scroll down to the Microsoft Store app and reset it
- Then, reinstall Netflix again.
Check your date and time settings
Ensure your date and time settings are set to automatic:
- Go to the Windows Search box
- Type date and time settings
- Toggle on the two options that allow you to set the time and time zone automatically.
