Error when requesting certificate from Nginx Proxy Manager

[Hairball359]

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. crt.sh | 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:marshan.duckdns.org

I ran this command: certbot certonly --config "/etc/letsencrypt.ini" --cert-name "npm-10" --agree-tos --authenticator webroot --email "james_d_marshall@yahoo.co.uk" --preferred-challenges "dns,http" --domains "marshan.duckdns.org"

It produced this output:

Welcome to the community @Hairball359

You are missing the --webroot-path option which should name the root folder in your nginx server block.

If adding that still does not work then please post the error message you get

My advice? Don't use Nginx Proxy Manager, IMHO it's terrible in its implementation regarding certificates/ACME. Or open a ticket/thread with the NPM support system.

@Hairball359

i [..] have stopped using Nginx

Note that my advice was about Nginx Proxy Manager and not nginx itself. Two different things entirely.
