question about headless configuration

I want to run the Jetson Nano Developer Kit in a “headless” configuration. I followed the official tutorial but failed,my Jetson Nano Developer Kit is booting properly by connecting it to a TV through an HDMI cable.
So I don’t know what went wrong, is it only available on the first boot? Is it the login password? (But I cancelled the password and it still can’t.) Or is it because I am in China?
How to solve this problem?
Thank you in advance for your reply.

Are you intending to ssh to your Jetson Nano through ethernet port? or you want a remote desktop through VNC viewer?
Make your questions/issues clear to others then they can provide corresponding help as well.

Hi 312529167,

Could you describe more detail about your issue?
Can you boot into Headless Mode success?
If you want to using headless feature, you don’t need connect any display, it’s using on serial port.

You can check L4T documentation -> Reconfiguring a Jetson Device with oem-config section.
