      Connecting to MongoDB using connection URI SRV in Go v1.11 generates an error: cannot unmarshal DNS message.

      The following code works in Go v1.10 but not in Go v1.11: 

              mongoURI := "mongodb+srv://USER:PWD@ts-cluster-ci22a.mongodb.net/test?ssl=true&retryWrites=true"
        client, err := mongo.NewClient(mongoURI)
        if err != nil {
                log.Fatal(err)
        }
        err = client.Connect(context.TODO())
        if err != nil {
                log.Fatal(err)
        }

      Also, the same code above works with non-SRV URI in Go v1.11.

      This looks to be related to the change in the net package: https://github.com/golang/go/issues/10622

      The call below would work in Go v1.10 but failed in Go v1.11: 

              _, _, err := net.LookupSRV("mongodb", "tcp", "ts-cluster-ci22a.mongodb.net")
        if err != nil {
            log.Fatal(err)
        }
