Cannot connect to Solace Cloud - solace

Question

I am following the solace tutorial for Publish/Subscribe (link: https://dev.solace.com/samples/solace-samples-java/publish-subscribe/). Therefore, there shouldn't be anything "wrong" with the code.
I am trying to get my TopicSubscriber to connect to the cloud. After building my jar I run the following command:
java -cp target/SOM_Enrichment-1.0-SNAPSHOT.jar TopicSubscriber <host:port> <client-username#message-vpn> <password>
(with the appropriate fields filled in)
I get the following error:
TopicSubscriber initializing...

Below is the TopicSubscriber.java file:

#Override

});
session.addSubscription(topic);
System.out.println("Connected. Awaiting message...");
cons.start();
// Consume-only session is now hooked up and running!
try {
latch.await(); // block here until message received, and latch will flip
} catch (InterruptedException e) {
System.out.println("I was awoken while waiting");
}
// Close consumer
cons.close();
System.out.println("Exiting.");
session.closeSession();
}
}
Any help would be greatly appreciated.

java.net.ConnectException: Connection timed out
The log entry indicates that network connectivity to the specified DNS name/IP address cannot be established.
Next step includes:
Verifying that you are able to resolve the DNS name to an IP
address.
Verifying that the correct DNS name/IP address/Port is in use - You need the "SMF Host" in the Solace Cloud Connection Details.
Verifying that the IP address/Port is not blocked by an intermediate network device.
