There is a system crash in the cloud system, admin will sure fix it within a day. Users have been experiencing SSL handhake errors within the past hour. Feel free that there is no problem with your website setup as it is the hosting provider’s issue.
Please be patient and im sure it will be resolved.

In a nutshell, the default, self signed SSL certificate was removed. If you were using it on your website before, you can switch to using HTTP connections instead of HTTPS in the mean time.
You can read more about this in the outage notice I just posted:
You can switch your connection back to HTTP in the same way you set it to HTTPS in the first place. Our hosting servers don’t enforce HTTP or HTTPS by default, so any redirects are caused by your website software or configuration.
.htaccess rules are a common way to enforce HTTPS, but some scripts can also be configured to redirect all traffic to HTTPS.
