Hi There,
Currently, my client has been running in DNS only for as long as they have known. We wanted to change the main A record and the www CNAME to proxied to get the full benefits of Cloudflare. However, upon doing so the site breaks and I can’t see the site anymore. Is this just a temporary thing or is there a misconfiguration somewhere that would be causing it. The site is unifiedlawyers.com.au.
Many thanks
Byron
Welcome to the Cloudflare Community. 
Have you searched here for the error you see when the
Does the site work over HTTPS in 
DNS Only?
When you activate the 
proxy, is the SSL mode set to Full (Strict) in Cloudflare?
Thanks for the response. So I saw after I posted this that the actual response was too many redirects which were causing it to show a white page. With DNS only it’s clearly not a problem.
I read somewhere that it could be a certificate related issue, is that where you’d suggest that I start trying to resolve it?
Cheers

Click the linked text in your reply. 
That depends on:
If HTTPS is working with , then your certificate is fine and you just need to use:
If HTTPS is not working with , you will need to fix that first. Then you can enable:
Thank you so much, that’s a very detailed response.
In terms of full strict, it mentions this “Encrypts end-to-end, but requires a trusted CA or Cloudflare Origin CA certificate on the server”.
I believe we might be running with an Auto SSL script, I’ll need to double check, would I need to do anything to support the requirement that’s been outlined above?
AutoSSL would typically obtain a trusted certificate. You would know right away if it wasn’t. Your browser would make a big fuss about it.
If you run into any complications with AutoSSL renewal, you may need to adjust some Cloudflare settings. I use ACME, not AutoSSL, so I don’t have specific tips for that.
@epic.network thanks so much for your help. I tried again last night with your instructions and I was able to successfully activate the site using the full (strict) setting that you provided.
Much appreciated for your help on that one.
