Lets Encrypt SSL Certificate Automation for CP server.
Please make the system auto-generate and auto-install free Let's Encrypt SSL certificates on the CP server so that expired SSL do not cause the CP server to be removed from the Federation or violate Federation policy.
There is no need for human intervention (or the support tickets that are manually generated from OnApp technical support reps, to OnApp's customer when it expires) when this can easily be fully automated.
We have a nice guide how to install and renew Let’s Encrypt SSL certificates. The guide covers CentOS 7 and 6 installations steps and a cron script that automatically renews your certificate. I would suggest changing your certificate to Let's Encrypt SSL asap to prevent the old one from expiring.
