I have this flow that works nicely when I try to access the HTTP IN node via an external machine

```auto
curl "http://192.168.50.59:1880/callback_google_meet_url" -X POST -d "test"

```

However, if I try connect it locally it doesn't work:

```auto
curl "http://localhost:1880/callback_google_meet_url" -X POST -d "test"

```

or

```auto
curl "http://127.0.0.1:1880/callback_google_meet_url" -X POST -d "test"

```

I just got this error message:

```auto
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot POST /calback_google_meet_url</pre>
</body>
</html>

```

Here's the flow that I'm using

```auto
[{"id":"6bf330e3.7c886","type":"tab","label":"Debug","disabled":false,"info":""},{"id":"f2ba6c03.8e3da","type":"http in","z":"6bf330e3.7c886","name":"Callback with the Google Meet URL","url":"callback_google_meet_url","method":"post","upload":false,"swaggerDoc":"","x":500,"y":340,"wires":[["bc26fc08.625b4","f7130f73.285d2"]]},{"id":"bc26fc08.625b4","type":"debug","z":"6bf330e3.7c886","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":850,"y":400,"wires":[]},{"id":"f7130f73.285d2","type":"http response","z":"6bf330e3.7c886","name":"","statusCode":"","headers":{},"x":830,"y":280,"wires":[]}]

silly question (but someone has to ask) ...

is the `curl` command being executed on the same machine that node-red is running on?

does the debug show anthing when you curl to `localhost`?

can you change the debug to show complete msg - do you see clues in the full msg object?

I'm executing them on different machines:

Node-red machine: `curl "http://localhost:1880/callback_google_meet_url" -X POST -d "test"`  
other machine: `curl "http://192.168.50.59:1880/callback_google_meet_url" -X POST -d "test"`

No debug for the local curl, event with the complete message

I also changed the http response code for 200 on the response node just in case

localhost wont work if you are not on the node-red machine - am i misunderstanding you?

Are you running node-red in a container such as Docker?

Oh no, I'm not that dumb 😃

The localhost curl is being executed locally on the raspberry pi where node-red is installed

What does  
`curl "http://localhost:1880/"`  
show?

That's ok then, it is very odd, your flow works for me. Either you have something blocking POST to localhost or it is an issue with node-red. What hardware/OS are you running on and what version of node-red and nodejs. The node-red version is at the bottom of the dropdown menu, you can get the nodejs version using  
`node -v`

That should be ok. Does it work if you change it to a GET?

So having changed it to a GET  
`curl "http://localhost:1880/"`  
works, but  
`curl "http://localhost:1880/callback_google_meet_url"`  
doesn't? Even though you are definitely running the curl command directly on the machine running node-red.

When you run the node-red editor in a browser which machine are you running the browser on and what URL are you using in the browser?

For speed reasons I use a remote machine, but it works on both.

BTW I've installed a fresh copy of rasbian and node-red and it's now working. No idea on why it wasn't before though

Thank you for your help \<3
