When asking for help it is a good idea to provide information about your setup like
- what device and OS are you running NR on?
- what version of NR and node.js are you using? (you can get this from the node-red startup log)
- are you using Docker or Home Assistant?
- what browser are you using?
- what user ID is used to run the command?
When I run that on my Mac, I get a reply in Safari, Firefox, Chrome and Brave
