letsencrypt 续订证书时出现 404 错误

Question

Every time I try to renew my letsencrypt certificate it fails with a 404 error using nginx and certbot. I managed to fix it by modifying the configuration file to a basic one, but this prevents the certificate from auto-renewing, so every 3 months I have to repeat the operation. Could you help me to find out where the problem is?

My actual domain conf (acuar.io.conf) -- This code is working to operate the website but not for renewal

# Odoo servers
upstream odoo {
 server 127.0.0.1:8069;
}

upstream odoochat {

}

# HTTP -> HTTPS
server {
    listen 80;
    server_name www.acuar.io acuar.io;

    include snippets/letsencrypt.conf;
    return 301 https://acuar.io$request_uri;
}

# WWW -> NON WWW

    return 301 https://acuar.io$request_uri;

        proxy_pass http://odoo;
    }

    # Gzip
    gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
    gzip on;
}

The code I have to setup to get certificate renewal working:

server {
  listen 80;
  server_name acuar.io www.acuar.io;

  include snippets/letsencrypt.conf;
}

Thank you very much for your help

After a lot of tries i managed to make a workaround, I'm sure there may be better options but at least it works:

I commented the line where the code redirects HTTP to HTTPS:

 # HTTP -> HTTPS server { listen 80; server_name www.acuar.io acuar.io; include snippets/letsencrypt.conf; # return 301 https://acuar.io$request_uri; }

The problem, as long as I understood was Cerbot needs to access the server in HTTP but the server was already forcing all trafic to HTTP.

If anyone have a better way to make this i really apreciate the help. In any case I hope this will help someone in the same error like me.

Thanks
