I have several modules equipped with sensors running the IOT_demo software ( sensor mode ).
It worked for almost 1 year.
This the 12nd may ( about 11:00am HK time ), my modules cannot send datas to the espressif cloud server.
All my modules now are running in a loop seeking the next memorised wif networks.
on a terminal if I'm doing this :
telnet iot.espressif.cn 8000
telnet: connect to address 18.104.22.168: Connection refused
telnet: Unable to connect to remote host
the connection is refused
if I'm doing this :
telnet iot.espressif.com 8000
Connected to iot.espressif.com.
Escape character is '^]'.
it seems working
Is there any change between iot.espressif.cn and iot.espressif.com ?
Should I update my firmware ?
Or is it an issue with the cloud server ?
