I have create a subdomain for my database server. In local network, it works perfectly. However, when enabled cloudflare, I got error 520. Does anyone know how to fix it?
PS: I think this problem is related to client authentication since I have enabled the client authentication using my self sign certificate. Maybe because of this, the cloudflare don’t have the client certificate so unable to communicate with my server?
