Not really. What’s exactly the card properties? Any chance the url didn’t get in there properly? Your sample does show some strange things (not a real IP but I assume this is because you do not want to share that publicly). Is there anything in the other fields? I would imagine an empy body: {} but it doesn’t seem to require that with me.
I just replaced a robot vacuum that I used to control using webrequests, so I no longer have any real life samples working at home, but if I take your url and replace the ip with one of my own I do not het any errors (though my NAS problay has no clue what to do with the request 
).
