[Angh_9989]

i just made a programs of monitoring feature for waterhammer phenomenon using Labview and IoT with HTTP method (web server) and my problem is my labview can't get data from my esp32, from serial monitor in arduino ide it tells me about fail GET : 404, how do i fix this?

Start with showing what you are doing. Attach your VI and the communication protocol.

HTTP error 404 means resource not found, which means you reached an HTTP server but there is nothing at that URL.

Just to expand a little bit, this error comes from the server.

Sure.  Give it the right URL.  If you're sure it's the right URL then fix the server.  I don't mean to be mean, but are you sure you are the right person to be doing this?

So you are trying to POST data from Arduino to a LabVIEW web service? Using the word get is confusing, because in an HTTP context it would imply that LabVIEW initiates the connection to a server.

Here are the available endpoints of the server:

Do you have a typo on the arduino side perhaps? selenoid <> solenoid?
