scala - Getting The entire node set is unreachable error when trying to connect to MongoDB with reactivemongo in my play2 application -

when working locally have no problem testing application calling:

http://localhost:9000/r/123 

method:

def showsurvey(id: string) = action {        implicit val reader = review.reviewreader     async {       val cursor = reviews.find(bsondocument("_id" -> bsonobjectid(id))).cursor[review]       cursor.headoption.map(maybereview =>         maybereview.map(review => {           // fill form           ok(views.html.review.desktopsurvey(some(id), surveyform.fill(surveyform(review.grade, review.text, regular_auth, false, "", "")), grades))         }           ).getorelse {           //notfound temporary below:       val review = review(some(new bsonobjectid(id)), 3, "bla", some(new datetime()), some(new datetime()), some("0.0.0.0"), reviewstatus.not_claimed, some(1), some(1l))       ok(views.html.review.desktopsurvey(some(id), surveyform.fill(surveyform(review.grade, review.text, regular_auth, false, "", "")), grades))      }       ).recover {         case e => internalservererror(e.getmessage())       }     }   } 

but when running app in production doing clean compile stage , going url get:

[error] r.c.a.mongodbsystem - entire node set unreachable, there network problem? 

i find strange since plugin seems work properly:

[info] application - reactivemongoplugin started db 'blala'! servers:         [87.238.57.140:27017] 

by checking mongodb log found connection ok bson sent in invalid:

this made me @ code , problem was sending in invalid objectid, in case 123 . somehow error got swallowed application. when there possibility objectid sent in might corrupt check with:

val maybeoid: try[bsonobjectid] = bsonobjectid.parse(id) if (maybeoid.issuccess) {     // stuff }
