Transferring Domain Hosting from Netlify to Cloudflare

Hi, my domain is currently hosted on Netlify and I’m transferring it to Cloudflare. I properly configured all of my Cloudflare settings and had CNAME records to my <site> URL. I’ve also disabled the “Proxy” (orange cloud) settings in Cloudflare so my CNAME records are in “DNS only” mode.

When I made the migration, however, I ran into the following error in my developer console: ERR_SSL_VERSION_OR_CIPHER_MISMATCH

From what I understand, Netlify should still be serving my SSL cert so I don’t see how the cert could have been invalidated during the transition. Any advice?
