Challenge failed for domain

Help
1

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:
novihan.topche.net

I ran this command:
/opt/certbot/bin/certbot certonly --non-interactive --config "/etc/letsencrypt.ini" --cert-name "npm-15" --agree-tos --email "topche@gmail.com" --preferred-challenges "dns,http" --domains "novihan.topche.net"
Saving debug log to /var/log/letsencrypt/letsencrypt.log

It produced this output:
Error: Command failed: /opt/certbot/bin/certbot certonly --non-interactive --config "/etc/letsencrypt.ini" --cert-name "npm-15" --agree-tos --email "topche@gmail.com" --preferred-challenges "dns,http" --domains "novihan.topche.net"

Beats me, as NPM seems to "swallow" the actual error message.. IMO it's a terrible piece of software..

Please check the log at /var/log/letsencrypt/letsencrypt.log.

Here is the log:
Domain: novihan.topche.net

Detail: Invalid response from Nginx Proxy Manager [93.155.149.50]: "<!doctype html><html lang="en" dir="ltr"><meta charset="utf-8"><meta name="viewport" content="width=device-width,user-scal"

To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.

DNS is not the issue, nginx or NPM is. And I'm not burning my hands on that. Maybe someone else on this Community has too much spare time to walk you through a few weeks of debugging this )(#*$()# (not a NPM fan..), but I recon you're likely to have more success on the NPM support channel(s), if they exist.

Are you on the right server?
There are no vhost config shown.
It doesn't even cover port 80.

yes. I'm on correct server. It is behind router and nginx listen on port 8088.
The router do redirection from 80 outside to those internal 8088 port.

OK then you can't use --nginx (without adding --http-01-port 8088)
OR
Switch to using:
--webroot -w /var/www/html
