Исключение в потоке "main" com.rethinkdb.gen.exc.ReqlDriverError: Превышено время ожидания соединения

Question

Я использую Gridle и использую RethinkDB Driver (Java) - 2.2.3 и работаю в Netbeans (8.2). Я получаю этот код ошибки:

`Exception in thread "main" com.rethinkdb.gen.exc.ReqlDriverError: Connection timed out.

Ниже приведен код, который я запускаю, который подключается к базе данных. Извините, я не могу исправить вставку, поэтому я использовал hastebin, если кто-то хочет помочь исправить форматирование, это было бы здорово! (https://pastebin.com/XPgPqmc5). Огромное спасибо другому редактору за то, что он все очистил! - Java Side Code
