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: https://smartmind.today

I ran this command: Nginx -t
{more information - I created a subdomain 3l.smartmind.today and acquired certificate using certbot [sudo certbot --nginx --hsts --staple-ocsp --must-staple -d 3l.smartmind.today]. However, at some point, i decided to pull down the subdomain and redo it again and i therefore removed the certificate and the subdomain server block and folder. Now Nginx configuration has an error}.

It produced this output:nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/3l.smartmind.today/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/3l.smartmind.today/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
nginx: configuration file /etc/nginx/nginx.conf test failed

My web server is (include version): nginx version: nginx/1.18.0 (Ubuntu)

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

My hosting provider, if applicable, is: Godaddy / Cloudflare

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

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):0.40.0

You must still have an ssl_certificate line that names that file but it does not exist. Did you delete the certificate?

You should not need a cert for a subdomain since you have a wildcard cert for smartmind.today

Thanks Mike. I deleted the certificates - but Nginx trying to load it while its not existing. I have dug a bit and noticed that the subdomain certificate was being referred to in the default server block. I have commented these lines out and now Nginx configuration errors are resolved.

Thank you for checking.
