Heya @craftycodes,
In order to open a port there is something that needs to listen to it. Opening a port essentially means allowing network traffic to flow in and out of a specific communication endpoint on a Droplet. However, for that port to be useful, there needs to be a program or service on the computer that is actively listening to that port.
Think of a port as a door, and the service as the thing behind the door. Opening the door (port) doesn’t do much if there’s nothing on the other side to interact with. When a service is set to listen on a specific port, it means that it’s waiting for incoming connections or data on that port.
Anyway, in order open a port on your Droplet you need to use your firewall service, I would asume UFW.
First check the status
sudo ufw status
Then you can allow a port like so
sudo ufw allow 22/tcp
Where 22 is your port and tcp is the time of connection.
