HTTP Raw request default is throwing Response message:java.net.SocketTimeoutException: Timeout exceeded while reading from socket

Question

I sent a HTTP Raw request default with a host and port which I'm certain that I could connect using my windows 10 device.(Tested with Test-NetConnection and sent data via Ubuntu App, echo "DEMO Message" | nc mYHOST 6021) However, when I sent the request in Jmeter , I get below errors.

Sampler result is as per the below.

This demo host and port is working though and I used exact same in my real request too.

Similar issues come when I use JSR223 Sampler with below code.

def client = new Socket('DemoHostname', 9000);
client.setSoTimeout(2000);
client << "Hello ";
client.withStreams { input, output ->
    def reader = input.newReader()
    def response = reader.readLine()
    log.info('Response = ' + response)
}
client.close() 

Also with TCP Sampler of Jmter.

So based on the suggestion, I sent it as a Http request to websocket of Logstash. Good thing is add the record get added, but Jmter http request is running in an endless state. Seems since logstash communicate via TCP it's unable to provide a http response.

What are you trying to achieve by sending HELLO TEST to echo.websocket.org?

If you want to send a HTTP Request there, you need to do something like:

GET / HTTP/1.1
Host: echo.websocket.org
Connection: close

Demo:

If you need to load test a WebSocket server - you're using the wrong plugin, you should go for JMeter WebSocket Samplers instead and consider using more "alive" endpoint as this echo.websocket.org doesn't seem to be working anymore.
