How to Manage the Firewall on My VPSmini?
Each VPSmini has all ports blocked, except for the following ports: 80, 443, 8080, 8443, 3000, and a randomly assigned port for the SSH service.
If your application is running normally on port 3000 and it is a backend that should not be exposed, simply change its port to 3400 or another one. This will ensure that your backend is no longer accessible from the outside.
