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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:www.qifin.com.cn

I ran this command: certbot certonly --nginx

nginx version: WS

Certbot's nginx plugin does not officially support nginx forks. You may have to use certonly --webroot instead.

I think this technically counts as a bug as the version detection should not cause all of Certbot to crash, so I will file an issue to fix that. Thanks for the report.
