Ktor Netty Server is returning empty response

问题

The below snippet is taken from the quick start on the Ktor website.

val server = embeddedServer(Netty, port = 8080) {
    routing {
        get("/") {
             call.respondText("Hello World!", ContentType.Text.Plain)
        }
        get("/demo") {
             call.respondText("HELLO WORLD!")
        }
}
server.start(wait = true)

My console output looks like this

[07:32:13.144 INFO ] application          | No ktor.deployment.watch patterns specified, automatic reload is not active
[07:32:13.308 INFO ] application          | Responding at http://0.0.0.0:8080

I looked at this question and tried adding host = localhost but this did not fix my issue. I am accessing the link http://127.0.0.1:8080/demo like the quick start page directs but am getting ERR_EMPTY_RESPONSE.

I have also tried to send a curl -i http://127.0.0.1/demo request from the same machine but receive (52) Empty reply from server.
