MongoDB Service Exception

I have used MongoLab and set up my own MongoDB 3.0.1 on AWS and get the same error.

{
  "error": [
{
  "context": null,
  "message": "Failed to launch service "mongolab": Unexpected MongoDb Service Exception:\nSSL can only be 'true' or 'false'",
  "code": 500
  }
 ]
}

I tried switching to the old admin interface

{host}:{port}/launchpad/index.html

And still the same issue.
I have switched the connection strings around

 ds053688.mongolab.com:53688

and

 mongodb://<dbuser>:<dbpassword>@ds053688.mongolab.com:53688

still same error.
