Help too many certificates already issued

[GhezziA]

That's not a very considerate way of "consuming" certificates. It costs Let's Encrypt resources to generate a certificate. Heck, it costs Let's Encrypt considerable resources for the next 90 days, because of signed OCSP responses required for every issued certificate.

Just because Let's Encrypt certificates are free for you , it doesn't mean it doesn't cost something, in this case Let's Encrypt. Imagine if thousands other people are thinking like you (with 7 billion people on the world not an unlikely scenario): it would cost Let's Encrypt a lot of resources, just because you're recreating your VM without storing the certificates on a permanent location!

For testing there's the Staging Environment, please use that if you're not ready for production grade services.

I apologize for this mistake, I have been using it for years but it had never happened to me, every time I recreated the machine, I revoke the certificate and thought it was not a problem. However, among the many snapshots I found ubn .p7b valid until January. The problem is that I can not install it on skype4b, I believe because I am missing the primary key. What advice?
