Webhook trigger via Shelly URL Action did not work

Hello everyone,

I’m contacting you here because unfortunately I couldn’t find a solution to my problem on the Internet.
I would like to activate a webhook trigger in HA with a Shelly Button 1.
I have copied the URL for the webhook from HA and entered it under URL Action in Shelly. However, nothing happens, no matter how I set the webhook in HA.
Other Shellys can easily be addressed via the URL Action
I have selected all options. Even if I enter the URL in the web browser, the webhook is activated. Unfortunately, nothing happens via the Shelly.

I have entered the following URL in the Shelly:
http://homeassistant.local:8123/api/webhook/example455443wesf67m89lfm43423
and / or
http://192.168.X.XXX:8123/api/webhook/example455443wesf67m89lfm43423

In HA I have activated all options for the webhook:
GET
HEAD
POST
PUT

Are there any settings I need to make on shelly or in HA so that the webhook in HA also responds to the URL action from Shelly?

I hope you can help me with this. Otherwise the button would unfortunately be useless for me.

Greetings
MACho

Hey together,

I can’t get any further with this topic and hope that someone else can help me.
