Shelly EM device off line

I have a Shelly ‘Em that was working perfectly. I had to reset my router and lost the connection to the Shelly app, device off line.I have now deleted my original device from the app and reconnected. It’s still showing device off line.

Hope somebody can help

Many thanks
