Hi @dadoonet,
80 is default port and i am getting below when I browse with port 80:
"This page is used to test the proper operation of the Apache HTTP server after it has been installed. If you can read this page it means that this site is working properly. This server is powered by CentOS."
That means port is working fine but when I try to send data with rest http call, hostname:80, I am getting 404. Not sure why so?
