      Hello,

      I´m trying to connect to a mongod instance on CentOS with the Java driver from my windows-pc. The mongod is configured as follows:

         ssl:
    mode: requireSSL
    PEMKeyFile: /tmp/ssl/mongodb.pem
    CAFile: /tmp/ssl/cert-chain.pem
    allowConnectionsWithoutCertificates: true

      A connection from my windows with the commandline works:

      mongod <server:port> --ssl --sslCAFile <certicate-ca>

      Also from MongoChef, but I get an exception when I try to execute the following snippet:

      MongoClientOptions clientOptions = MongoClientOptions.builder().sslEnabled(true).sslInvalidHostNameAllowed(false).build();
MongoClient mongoClient = new MongoClient("<mongod-dnsname>", clientOptions);

MongoDatabase db = mongoClient.getDatabase("test");
MongoCollection<Document> collection = db.getCollection("testColl");

System.out.println(collection.count());

      The stacktrace is:
