Why is my site down? (SSL error)

Your SSL certificate chain might not be configured correctly. While modern browsers tolerate this, it can cause problems with the older ones.
We recommend using the ssllabs.com validator to identify the issue.
You can, however, also disable SSL validation in the advanced settings of your monitor.
