Error 526, my website is down

Hello, how are you?
My website displays an error 526. But after checking all the information on my Clouflare account, it appears nothing is down, my bill are paid, the SSL certificate is valide,… But now, I don’t know where is my problem.
Could you please help me?

Thank you very much,

It most definitely isn’t on the origin given the error…

For some help.

i’ve checked the link you sent me. I’ve checked all is suggested but all these points work for me. So I don’t know where does the problem from.

What is your domain name?

ewingpowerprod .com

I see the error, I’m confirming the diagnosis. The origin has a wrong cert. I can’t see the origin directly, so can’t help more… you could disable proxying and we can see what cert is shown.

Ok. Which proxy do you think I have to disable?

If you are using full strict, the certificate subject does not match your hostname and thus isn’t valid for a full strict connection and will fail.
