We created a certificate on a linux box and exported it to an IIS 10 Webserver run on Win2k19.
Now I would like to renew that certificate by passing the CSR file created on IIS, but I get the laconic message “failed to parse the csr file”.
How can I find out more about the problem?
I ran this command: certbot -d mdrds.mandarinaduck.com --manual --preferred-challenges dns certonly --csr /mnt/certs/renewal.csr --dry-run
It produced this output:failed to parse CSR file
I can login to a root shell on my machine (yes or no, or I don’t know): yes
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): 0.27
