Yes I have. Not I tried to set to China region which also can't be setup.Have u recently update the device firmware?
I used to have a few Xiaomi camera. they always have this issue. Sometimes I not sure if the China great firewall issue or what.
Last check only those international set can use SG datacenter.
I know how it feels. I have a few mijia camera in my store room. They work awhile and start to go offline.
They have quite good video and function. But the reliability is bad
Looks like everything seems ok if I did not connect the camera directly to the router which support usb 3.1. Currently is set to directly connect to a power usb adapter into a power socket
Is it due to router setting? Or not enough power supply from the router usb port to the IP camera?
