I have a error and I tried to figure out what was wrong for 2 hours and I can't fix it.
I ran my spring boot app using java -jar command, it's a package and it couldn't start.
I set the properties file to set the port for 80 and my firewalld is disabled and I ran on centos7 machine. and I tried netstat command and there was no service for port 80 so it is not a port problem i think.
This is error log:

Description:
The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 80, or configure this application to listen on another port.

Ports below 1024 are restricted to root user only. Try running your jar as root.
If you run your app on, let's say, Tomcat, then Tomcat needs root privileges to open port 80.
