Nginx Server Is not accessible, can't update certbot

Help
1

My domain is:parrity.com & next.parrity.com

I ran this command:certbot -d next.parrity.com

It produced this output:

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
  Domain: next.parrity.com
  Type:   unauthorized
  Detail: Invalid response from http://next.parrity.com/.well-known/acme-challenge/Hk8Nf40JC_92ADGg-iEu9T29Y9EBwPzG2r4hLkjpolc [46.101.240.67]: "                                                                                                                              <html>\r\n<head><title>404 Not Found</title></head>\r\n<body>\r\n<center><h1>404 Not Found</h1></center>\r\n<hr><center>nginx/1.19.10</c"

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to th                                                                                                                              is nginx server and that it is accessible from the internet.

My web server is (include version):Linux

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: DigitalOcean

I can login to a root shell on my machine (yes or no, or I don't know): Yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):No

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 1.24.0

Hello everyone, I have the following situation on my hands,

I have several droplets hosted on DigitalOcean with my platform - parrity.com

parrity.com points to an I.P of a doplet that has an ip: 46.101.240.67 & sub-domain caled next.parrity.com

For some reason the certificate on that droplet doesn't want to renew, and also the sub-domain and typing the I.P does not work as it gives 404.

However, opening parrity.com works and loads the working app with the outdated certificate.

I suspect this might be a record issue, but not sure where to start. Please help.

I checked if the nginx is running

That is all I'm getting

There definitely should be more. You could try save the output of a command to a file:

sudo nginx -T > nginx-full.conf

then download the resulting nginx-full.conf file from your server, and paste it here.

Sorry. Your DNS records look fine to me, I think it's something to do with the nginx configuration, which I'd like to see.

Hey guys, I hired someone to fix the issue, the problem was that a container inside Nginx was linked to a system for comments that had a subdomain linked to it with a certificate that had expired 6 + months ago
