craft\web\ServiceUnavailableHttpException on initial load

[kylerits]

Description

I am having issues with the initial load of my craft site. I am not able to access to home page by directly link, however I login through /admin and link to the homepage via the 'View Site' button, the site loads just fine. The stack trace is shown below:

Adding 'isSystemLive' => true to craft/config/general.php seems to have resolved this issue.

Had it been set to false ?
