I signed up to this forum just to add to the people having issues. I purchased Sonoff POW and tried both methods of getting online - using the cell phone, and two different routers. Nothing is working. So I figured I got a bad unit and a new POW from ebay arrived and the same thing is happening. Pairing goes great (using IOS) and then nothing but flashing twice blue led. I really hope someone is watching this thread and will fix it. Otherwise they are going back. If I had local access (without cloud) I would keep them, but being forced to use the cloud makes these items worthless when service goes down.
Thank you.
THE SOLUTION IS:
Substitude IP address of eu-disp.coolkit.cc to 52.29.61.50
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:
current:
telnet 52.28.157.61 8081
old:
telnet 52.29.61.50 8081
SOLUTION
Here is an example how to make a substitution in Mikrotik router:
Open Winbox
Get to "IP > DNS" menu
Click on "Static"
Click on "+" (add static DNS entry)
Name: eu-disp.coolkit.cc
Regexp: <leave empty>
Address: 52.29.61.50
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!
I am two days ago trying to connect the sonoff pow and nothing, connects to the router but does not access the server. The other sonoff basic devices that I have normal function. The worst part is that there is nothing from the tour.
Thank you Ivan for the information and you are correct (tested with telnet) - unfortunately my cheap airport extreme does not allow this functionality. I can just hope that they fix the server someday.
Do you know how to make this change in the Linksys E900 router?
Good news.....my POW just turned solid BLUE and is working and showing online on my phone! Thank you all for helping and have a great holiday season.

I've ordered 3 SONOFF and tried to associate them with my eWeLink account.
One of them always appears offline and I don't know what to do to solve that.
It's necessarly a problem with this device (or my account) as the other ones work well.
This device is well detected on my local network, but the LED keep blinking twice and repeat.
Maybe it's linked to the firmware upgrade that failed before.
