Have you tried factory restting the device and starting over?

Has your SSID changed or did you get a new router? 

the easiest method is to factory reset it and then bind it back in. 

if your SSID changed. 
There are a few ways to bring it back into your new network. If you still have your old router turn it on with the same password. once that is done go into the Shelly EM and then change the Wifi SSID to the new SSID. 

If you don't have the Old router with the SSID and password. You could use your phone to make a hotspot. Only thing is to make it the same SSID name and Password as the original Wifi. 

But the best would be to have the same / old router with the same SSID and password to then change it to the new one.
