I deleted the folder /etc/letsencrypt

[liviu-damian]

I was not able to renew my certificates and I deleted everything, I need to start over again and reinstall everything. How I can generate the keys?

My domain is: bivucu.com

I ran this command: sudo nginx -t

It produced this output: nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/bivucu.com/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/bivucu.com/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, laest version

The operating system my web server runs on is (include version): Ubuntu 20.04 LTS

My hosting provider, if applicable, is: namecheap.com

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 control panel

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 0.40.0

Welcome to the Let's Encrypt Community, Liviu

To begin, you will need to remove any references to the certificate and its private key from your nginx configuration then reload nginx (sudo nginx -s reload).

What is the output of:

sudo nginx -T

@liviu-damian

nginx, laest version

Is that least OR latest?
[huge difference - LOL]

Actually saying anything aside from the actual version number is undesirable.

Hi,

Thanks for help but I took radical measures, I killed the server entirely on Digital Ocean and I created a new one and redeployed everything again from scratch.
It is working now.

Liviu.

Glad it's working.
