May I ask you to re-check if Cloudflare is allowed to connect to your origin host to as follows in the below article?

• https://support.cloudflare.com/hc/en-us/articles/201897700-Allowing-Cloudflare-IP-addresses

Nevertheless, Cloudflare IP addresses list can be found here:

• IP Ranges

As I said, not the issue.

So, your Website is not secured?
May I ask before moving to Cloudflare, was your Website working over HTTPS connection or not?
If yes, is the SSL certificate self-signed or from Let’s Encrypt, or purchased maybe for your domain name + www prefix + some other possible (or not) sub-domain?

May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

Incorrect. My website is secured.
There was no before cloudflare. SSL cert is from lets’ encrypt. SSL option is Full, I’ve tried every option. Changing this setting did not remedy the issue.

I’ve read all the community tips, and about 12 hours of testing,rechecking, google article reading etc.

@fritex

Both are proxied and set to ?

Correct

@fritex

From your screenshot I see:

• HTTPS → response status of 400.

May I ask if you can post a screenshot of this 400 error? Is it coming from your origin host/server or rather from Cloudflare?

This is coming from the Cloudflare diagnostic. From the client, I get 522.

@fritex

How about below two options at Cloudflare dashboard for your domain name?:

1. Always Use HTTPS
2. Automatic HTTPS Rewrites

Are they enabled or disabled?

I am unable to find these in the dashboard.
