New server, lost old keys


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):
Ubuntu 16.10 LTS
The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

I had a valid certificate on old server but i lost my keys, waited 90 days for expiring but this didn’t help also.

What is the best route to request new keys now, i am getting the following errors on my domain:


I run Traeffik with lets encrypt, i can access the port 80 acme challenge.



The best practices is to issue a new certificate using certbot.

You can’t find private key with only public key. (Since LE doesn’t store privakey key from client, just auth their csr)

Thank you
