Not getting SSL Cert

My Question was. I have a domain registered on GoDaddy. and I’m run this domain name with hostinger.

in this case, I’m updating my hostinger DNS on Godaddy. for domain parking.

so now I want to use SSL.
then I replace my hostinger DNS with Cloudflare DNS.
but after a few minutes, my domain down some time run well and sometimes down.

Hi @shivam.shubham1998,

I see a 525 error on that site.

A 525 error is typically caused by a configuration issue in the origin web server when its SSL certificate is not properly set up. Review the suggestions in this Community Tip for advice & insight.

In short, you need to configure an SSL certificate on your server.
