scala - How to fix the Dropping Close since the SSL connection is already closing error in spray -

i’m making call api, of time keep getting error: “dropping close since ssl connection closing” , “premature connection close (the server doesn't appear support request pipelining)”. 90% of time error, meaning: in rare occasions query return data supposed to.

to make sure wasn’t api’s server issue, replicate exact same query using node.js (express , request libs) , works every time. makes me sure spray bug.

here's example of code:

case class myclass(user: string, pass: string)  class myactor extends actor {   import spray.client.pipelining._   import spray.http.basichttpcredentials   import spray.http.{httprequest,httpresponse}   import scala.concurrent.future    import context.dispatcher    def receive = {     case myclass: myclass => {       val credentials: basichttpcredentials = basichttpcredentials(myclass.user, myclass.pass)       val url: string = "https://myapi?params=values"       val request: httprequest = get(url) ~> addcredentials(credentials)       val pipeline = sendreceive       val response: future[httpresponse] = pipeline(request)       val finalres: future[string] = response.map{ r =>         println(r)         r.entity.asstring       }       finalres pipeto sender     }   } // end receive } //end actor
