In this article, I explain how to solve the Yi Home camera error 20009.
This problem is related to the camera's Chinese version known as "Xiaomi MiJia Smart Home Camera 1080p" or with a similar name when used outside of China.
Let's take a look at how to solve this issue.
The error 20009
The message error "Network connection failed, please check network settings and reconnect it (-20009)" shows up in the Yi App, and you can't see the live video.
Depending on the camera's firmware version, you may see the message "Couldn't open camera -20009, try again later", which indicates the same problem.
What causes the issue
There's a Chinese and international version of the Yi Home Camera.
These cameras use different firmware versions, and the Chinese version is designed to work only in China and must communicate with a server located in this country.
If you buy the Chinese version and try using somewhere else, you may see the error.
How to fix the error 20009
You can download a special firmware and change the camera configuration file.
