Nginx SSL Setup with Certbot

I need an SSL certificate installed using Certbot on my existing Nginx configuration. The SSL is required to secure both my website and API.

Requirements:
- Apply SSL to my current Nginx setup
- Use Certbot for installation
- Ensure site and API are secure

Ideal Skills and Experience:
- Strong experience with Nginx
- Proficient in using Certbot
- Knowledgeable in SSL configurations

Automatic renewal setup is not needed; I'll manage that myself.
