Confluence - This site can't be reached problem

Hello

This issue is on my Dev instance of Confluence. I have it installed on Linux Rhel 7, and it worked fine for over 2 months. All of a sudden it stopped working

the error in the logs is pretty consistent as the following:

I figured it out... Apache was down
