Hi, I activated the security certificate, but it's not working

I linked my site to Cloud Flyer, and then I did the safety certificate.(https)
But i worked for a few minutes, and then it didn’t work.
I want to do it.
Although I’m activated, all the right settings.

What’s your domain?

smmsocialpro.com

Your domain lacks DNS records. You need to add DNS records on the DNS tab which point to the origins you wish to serve.

Can you technological more because the written certificate is not valid

You added the zone to Cloudflare. Cloudflare scanned your DNS records. Cloudflare issued an SSL certificate. You then deleted the zone and added it back. The tool was unable to scan your DNS records from previous version. On the DNS tab you have no DNS records. Visit the audit log to see what Cloudflare added the first time before the zone was deleted and manually add them back or visit your hosting provider to find the list of records and export/import them.

Unfortunately in the process of deleting and adding back the zone you’ve lost the previous DNS records. I don’t see any indication the certificate is not valid.

It is written to me in the browser that the security certificate is not valid, but there is https, but there is a line on it, and it does not work written that the site is not safe

Hi,

Checking your website i’m having an HTTP 525 error:

You can find in the link below what are the common causes for the SSL handshake failed:

Checking the first cause:

  1. No valid SSL certificate installed
    i can see your origin doesn’t have any certificate installed;

The solutions here are:

  • Install a self-signed certificate, or you can use our origin certificates

or

  • Change the SSL/TLS encryption mode to Flexible

After changing the encryption mode to Flexible wait around 3 minutes and visit the website using private/incognito mode.
