Sonoff is always offline

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 

Can you help me ?

Found Fix - Resolved
Had the same problem device not coming online.
1- hold button for 20+ seconds to reset to factory
2 - reboot your home router (this fixed the problem)
3 - setup and add your device from scratch - by logging in locally to the device, configuring you WiFi - CHECK that your WIFI Name and PASSWORD have no leading spaces.
Everything works fine now, good luck guys.


 The device drove me crazy, they work well - but TRY REBOOTING your routers and access points if you have them
