Also, how did you obtain the certificate in the first place and how did you renew it? This is important information. because crystal balls are a myth and we can’t just guess what’s wrong with your system.
And another thing: you’ve renewed your certificate five times today!

Now you’re going to hit the 5 exact same hostname per certificate per week rate limit. I hope you still have those certificates and private keys around!
