I have my own free Letsencrypt SSL which I use currently while my website is under development.
Before I buy SSL from Cloudflare, I wish to be able to use some of the Cloudflares services while using my own SSL. (Mainly to prevent DDOS).
The problem is that my websockets aren’t working while using my own SSL and Cloudflare.
I get error : ERR_CERT_COMMON_NAME_INVALID each time my browser tries to connection to my websocket server.
I am pretty new to Cloudflares features and I am unsure how I can bypass this. I want to have “loading screen” when someone is entering my website to prevent DDOS, but I want after that to maintain HTTPS with my own SSL (due to private key and cert info which I need for websocket).
Already thankful for any constructive ideas.
