Action not executing

I have entered the URL http;//192,168.0.191/relay/1?turn=toggle under the Action/Button 2 Switched On URL (and enabled it)
The IP address refers to another Shelly DImmer 2 activating a LED light. This LED works normal with the connected dimmer. (using the connected button, the app or the web interface)

The button 2 is a push button.
I can try whatever I want, but pusching button 2 long or short, one time or repeatedly, it does not switch the LED on or off.
I have tried by enabling the action under Button 2 Long Pressed URL and Button 2 Short Pressed URL, but these actions fail to save under button 2 (see other topic on this forum)
Can anyone provide advise how to solve this?
Thanks

Thanks for the advise Stefan

I tried both descriptions http://192.168.0.191/light/0?turn=toggle and http://192.168.0.191/relay/0?turn=toggle but none of them execute. (The ; in my first quote was a typo and the Channel is indeed 0 and not 1)
I meanwhile tried it also with a Shelly I3, without success.
I must be overlooking something very basic...

Zitat von markp

I have the same problem. Someone in another thread suggested to reboot the Shelly after defining the action but this has not worked for me.

I have opened a support ticket with Shelly and they replied that they suspect a firmware issue but I haven't received further updates.

Hello Mark. Please provide the feedback and resolution offered by Shelly, if you receive one.
Thanks
