[mongodb-user] Mongo Java Driver Failing to Connect to MongoD

Hello All,
I have a java project and am connecting to  mongod process using the
following
code
private static Mongo mongoObj = null;
private static DB db = null;
mongoObj = new Mongo("localhost", 27017 );
db = mongoObj.getDB( "MyDataBase" );
I was using this code for the last 4months and have created thousands of
documents but suddenly I am unable to connect to MongoD process.
But when I change from IP address to use "localhost" it works.
java.io.IOException: couldn't connect to [/"IPADDRESS OF THE MACHINE":27017]
bc:java.net.Conne
ctException: Connection timed out: connect

Are you running on Mac OS by chance?

There is a known issue (caused by an oddity in the code of how Java for Mac
looks up network addresses) that makes "localhost" resolve to the PUBLIC IP
of your machine rather than 127.0.0.1 … if your Mongo instance is only
listening to 127.0.0.1, you'll get an issue along these lines.

Otherwise, check what interfaces your Mongo server is set to listen on.
Many distributions start up listening only on 127.0.0.1

Check that the startup option or config value bind_ip isn't set.

I am using Windows 7 OS.
And I am clueless why suddenly it has stopped.
Could you please let me know if this is a known issue ? and there is a
solution to it.
Thanks

Its probably a firewall or ip change on the machine.
Are you sure the ip is the same?

HI,
Thanks for the suggestions..
But no the ip has not changed and neither the firewall settings...
But yes I updated my Windows7 version... Can that cause an issue ?
Thanks..

Try connecting specifically to 127.0.0.1
Does that work well?
