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.

The thread that you linked to does mention that the user's configuration file was long, but apperas to concludes that the problem with the nginx configuration was that it was lacking
In order to use certbot --webroot, your existing web server has to be capable of serving the static challenge files from the specified webroot location. If its configuration prevents that, its configuration has to be changed in order to use --webroot.
