Kindly, may I ask have you checked within the steps from below articles regarding this error showing up for your Website?:

It should have to be something with SSL certificate at your host/origin and Cloudflare SSL options.

May I ask, before moving to Cloudflare, have you had an SSL certificate at your host/origin server for your Website? Check and make sure you setup and have the Full (Strict) SSL.

Here is a way to re-check if correctly setup the SSL with Cloudflare:

What SSL option have you got selected at Cloudflare dashboard for your domain at SSL/TLS -> Overview tab?

As already asked, have you had an SSL certificate? Is it still valid?

May I ask what is your domain name?

Is your Web server working over 443 or some other port compatible HTTPS with Cloudflare one’s from the list below?:

Just to make sure, is Cloudflare allowed to connect to your origin host/server?:

Can you check if you have ca-certificates installed and updated?

Is your app listening on https 443 port?

What is your output of running openssl version -a and which openssl?

What happens when you temporarly disable Cloudflare? (Pause or put to Development mode or make :orange: records to :grey:)

Do you have SSL enabled for your application at your Web server (Apache config or Nginx vhost file)?

As there are a few of you with seemingly similar issues, can you paste the response from example.com/cdn-cgi/trace (replace example.com with the domain you are having trouble with) so we can see which Cloudflare datacenter you are hitting?

Also, when you pause Cloudflare, is your site working with HTTPS?

That domain does not respond for a very long time for me and then returns the 525. I’m connecting through AMS, so I don’t think it is connected to a specific datacenter.

If you pause Cloudflare, does your site work with HTTPS? You can pause Cloudflare from the Overview tab of the Cloudflare Dashboard, bottom right under Advanced Actions.
