Hi Support Teams
I buy Sonoff products to sell in Viet Nam about 5 months ago
This time, I bought 30 pcs. I try to setup it but all is always offline. I try in iOS or android and different account, it still offline . I setup sonoff successfully many times before. I thinks error in hardware, service or sortware. I sent feedback in eWelink with email firstname.lastname@example.org.
Can you help me ?
Yes, I have this problem. How can I resolve?
Sonoff FAQs, look for section Device offline - follow link.
THE SOLUTION IS:
Substitude IP address of eu-disp.coolkit.cc to 220.127.116.11
Right now for some reason current eu-disp.coolkit.cc IP doesn't accept connection to 8081 port, but the old one - does. You can check it by:
telnet 18.104.22.168 8081
telnet 22.214.171.124 8081
Here is an example how to make a substitution in Mikrotik router:
Get to "IP > DNS" menu
Click on "Static"
Click on "+" (add static DNS entry)
Regexp: <leave empty>
TTL: <leave by default [1d 00:00:00]>
Click on "OK"
Close the DNS Static subwindow
Click on "Apply"
Profit! Now your POW is online!
The same here. Work only one day. Then offline 3 days in a row. Very bad.
