SSL_ERROR_NO_CYPHER_OVERLAP
Howdy, I'm trying to configure my website to use the zero trust access module to prompt for MFA when accessing admin pages. Zero trust is unconfigured at the moment as I keep getting stuck adding my website to cloudflare.
I've configured my domain registrar to use cloudflare's nameservers and am proxying my connection. However when I try access my site (sp.zone) I'm getting the error "SSL_ERROR_NO_CYPHER_OVERLAP". The site is a simple blog and is using a lets encrypt cert.
If I disable the proxy, the site works fine but then I lose out on the functionality of cloudflare. Is there a way to solve this without using a cloudflare certificate?

Hey 👋
Is there a way to solve this without using a cloudflare certificate?No, Cloudflare will always need to use its edge certificate as it needs to decrypt the request and return responses. Although Biz or higher can upload their own certs. Your underlying issue though is just that CF doesn't have a valid certificate for your site, hence the error. You get one for free from your Universal. If you go to your website in the Cf Dash, SSL/TLS -> Edge Certificates. At the very bottom, do you have Universal SSL on? At the top, do you have any universal certs with error statuses? Magic Link: https://dash.cloudflare.com/?to=/:account/:zone/ssl-tls/edge-certificates
