This thing broke my development and testing environment.
I am in the middle of developing a plugin (https://www.crawlspider.com) that catches SEO changes, certificate changes and errors (crawlspider)
Suddenly the plugin was catching SSL errors for all the domains I was monitoring. Upon checking the domains in the browser everything look fine. There was a green secure icon on all of them.
It was only after several tests and chat with my admin, it became clear that this is a root certificate issue and somehow connected to letsencrypt based certificates.
