SocketTimeoutException when I use Scalaj request

I'm trying to make a simple https request using this library https://github.com/scalaj/scalaj-http . The request contains some json data.

Here is what I'm doing:

  val jsonHeaders = """{"jsonrpc": "2.0", "method": "someMethod", "params": {"dataIds":["12348" , "456"]}, "data2": "777"}"""

  val result = Http.postData("https://someurl.com/json-rpc", jsonHeaders)
    .header("content-type", "application/json")
    .header("X-Application", "myCode")
    .header("X-Authentication", "myCode2")
    .option(HttpOptions.readTimeout(10000))
    .asString
    //.responseCode -- the same error

  println(result)

And it always returns me a timeout error:

If I do just

val jsonHeaders = """{"version123": "12.0", "method": "someMethod", "params": {"dataIds": ["12348" , "456"]}, "data2": "777"}"""
val result = Http.postData("https://someurl.com/some-url2", jsonHeaders)
        .header("content-type", "application/json")
        .header("X-Application", "myCode")
        .header("X-Application1234", "myCode2")
        .option(HttpOptions.readTimeout(10000))
println(result)

it returns

Request(POST,<function2>,<function1>,List(),List((X-Authentication,myCode2), (X-Application1234,myCode), (content-type,application/json)),List(<function1>, <function1>, <function1>),DIRECT)

What do I do wrong and is there any another simple way to send https request? Even if involves spray framework, it would be ok (I don't find any example of how to do that in spray, though).

UPDATE:

An example has been taken from here Doing HTTP request in Scala

You need to specify a connection timeout alongside your current read timeout with: .option(HttpOptions.connTimeout(10000)).option(HttpOptions.readTimeout(50000)). Change the 10000 to a value that works for you. The default connection timeout is a pretty aggressive 100.

You do already have a read timeout specified, but the exception says it is timing out on establishing the connection, not on the the reading of the response.

See docs: https://github.com/scalaj/scalaj-http#custom-connect-and-read-timeouts
