Com.mongodb.MongoTimeoutException: Zeitüberschreitung nach 10.000 ms beim Warten auf die Verbindung ⇐ Java

[Anonymous]

Ich ging davon aus, dass diese Frage mehrmals gestellt wurde, aber ich musste sie noch einmal stellen. Da die für diese Frage bereitgestellten Lösungen mir keine genaue Antwort gaben, um diesen verdammten Fehler zu beheben.

Ich verwende mongo-java-driver-2.12.4 und mongo.jar, wenn ich versuche, ein Dokument in die Datenbank einzufügen, erhalte ich die folgende Fehlermeldung. Jede Hilfe wird geschätzt.

Fehler:

Exception in thread "main" com.mongodb.MongoTimeoutException: Timed out after 10000 ms while waiting to connect.
