Hello. For the first time engaged azure. Installed a virtual machine that without the prefix "classic"
Centos 7 deployed on it. Created a security group and opened incoming ports: 80 and some other
On centos installed php 7, httpd, mysql
All services are started normally, but I can not access the site, say, from my home PC. What am I doing wrong? If you connect from the home PC via telnet to port 22, everything is OK (it is understandable, the default port of Azura is the only open port), but on port 80 the connection does not go. Firewall is disabled. Tell me in which direction to dig? Thank you very much
