Shelly Plus 1 webhook not working

Shelly Plus 1 doesn’t send web hook. When I copy the URL directly from Shelly app unto clipboard and past in a web browser address field it works fine. https://maker.ifttt.com/trigger/{event}/with/key/{mykey}

Also tried: https://maker.ifttt.com/trigger/{event}/json/with/key/{mykey} Also tried both using http://

I have tried both “button is pushed” and “input on”. Have rebooted device. Rebooted router and even tried factory reset and reinstalled device. Relay operates fine but web hook is never sent or never received at IFTTT. Again the web hook trigger works fine when sent from web browser.

Thanks but as stated above I did try both http:// and https://, neither worked, both worked from web browser.
