Error 526 Invalid SSL certificate - But I just renewed the certificate!

Hi, I’m seeing “Error 526 Invalid SSL certificate” in my site https://www.leememas.com/ but I just renewed my let’s encrypt certificate.

Is there a way to check what certificate is cloudflare seeing and why is it invalid?

Does your server IP address end in 183?

Yes! 162.243.255.183

In that case it appears as if you had a certificate in place, however it is not valid for that domain but for a different one.

That is possible, I had too many domains included in the same certificate … But I don’t know how to debug this, as CloudFlare is in the way. How can you check what cert is CF seeing?

You can pause Cloudflare for your domain, in which case you will connect directly (once DNS propagation is done).

Right now this is returned

Thank you very much!
I was able to solve the problem.
