I lost my secure status and www.voelkerphoto.com is returning this privacy error (NET::ERR_CERT_COMMON_NAME_INVALID) in Chrome and Safari cannot verify server identity.
I’ve researched as much as possible but none of the solutions appear to be working.
Bluehost tech support says the issue is on CloudFlare side.
Suggestions? Please simplify your answers - I’m not tech savvy. 
Open up a Support Ticket at Cloudflare. There’s a good certificate there, but it doesn’t have your domain listed, which is causing the error.
If you want to experiment, try turning SSL off in Cloudflare’s Crypto tab, then turn it back on. That might refresh the certificate.
i am facing this issue on www.apksir.com after wait for one day it fixed automatically. because it take around 24 hours to activate free SSL.
