The Cloudflare origin certificate you have on your site should never have worked. I’ve seen dozens of customers try to use it and NONE have succeeded. I can’t find the link now, but Cloudflare’s own docs say that that certificate is for internal use of their systems only and will not work in situations like this.
You’ll see if you try to connect to our service using it, it will fail. This is not unique to Netlify or any specific browser:
$ curl -v https://likr.xyz --resolve likr.xyz:443:178.128.17.49
* Added likr.xyz:443:178.128.17.49 to DNS cache
* Hostname likr.xyz was found in DNS cache
* Trying 178.128.17.49:443...
* Connected to likr.xyz (178.128.17.49) port 443 (#0)
* ALPN, offering http/1.1
* SSL certificate problem: Invalid certificate chain
* Closing connection 0
curl: (60) SSL certificate problem: Invalid certificate chain

You’ll need a certificate from a third party which you purchase, OR you’ll need to proxy to likr.netlify.app instead.
That’s the limit of the tech support we can provide for you proxying from Cloudflare, due to all the reasons listed in this article: [Support Guide] What problems could occur when using Cloudflare in front of Netlify?
