This is my first time deploying an application, and when I was doing the server settings, happen problem with Nginx…

ufw status
WARN: Duplicate profile 'Nginx HTTP', using last found
WARN: "Profile 'Nginx HTTP' missing required field 'ports'"
WARN: Duplicate profile 'Nginx HTTPS', using last found
WARN: Duplicate profile 'Nginx Full', using last found
WARN: "Profile 'Nginx Full' missing required field 'ports'"
Status: active

How can I fix this error, connect the domain name and make the application available? How to install and configure Nginx for Spring Boot Application?
