Question
My droplet has debian os. I have a java application running which tries to exchange data with remote similar applications. This data exchange has previously worked across remote environments where each node has been a...
Accepted Answer:
Hello,
It sounds like that your Java app is binding to 127.0.0.1:4000 rather than 0.0.0.0:4000 so that's why you can only access it locally from the server itself.

Accepted Answer:
The cloud firewall should only block connections coming in on your public interface. A local firewall can be used if needed to restrict access on the local/private network.
