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 youre using specialized software to bypass its region restrictions.
These geographic restrictions are mainly due to licensing agreements.
Every country has its own Netflix content 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 youre using a VPN simply for privacy purposes.
Netflix cant tell whats 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 doesnt know that.
And so the platform assumes youre using a VPN to bypass its geographic restrictions and blocks your IP.
To rule out online grid connectivity issues, go ahead and power cycle your modem as well.
Or you might take this one step further and unplug the power cord to completely power cycle the rig.
Use a cable connection
Streaming video content requires quite a lot of bandwidth.
To see to it your connection can support this task, use a cable connection if thats possible.
Another thing you’re able to do is to disconnect all the other devices using the connection.
Dont forget to clear your internet tool cache as well.
punch your web app menu, selectHistory, locate theClear browsing dataoption, and punch it.
exit the web client, launch it again, and find out if you could connect to Netflix now.
Reset your Netflix app
If youre using the Netflix desktop app, try resetting it.
