mlab - mongodb could not connect to server

Question

I'm new to MongoDB. I'm trying to connect to my remote mongo database from my work machine( I tried for both mongohq as well as mongolab). I'm getting the error listed below. When I run the same command from my home machine it runs fine and does connect to remove mongo database. I'm not sure what is messed up on my work machine but I'd like to fix it. Thanks for you help.

MongoDB shell version: 2.4.9
connecting to: linus.mongohq.com:10097/mydb

exception: connect failed

Answer 1

As per question comments, your mongo shell client can't connect to the mongo instance. Assuming that your internet connectivity is fine, the most common reason for the failure is that the ports are blocked on your network.

Some ISPs automatically block these ports by default as an additional security protection for users that don't need them open. Contact your ISP or network admin, they should be able to help you out.
