Really this is very confusing to install let's encrypt SSL certificate in VPS. I will try everything from this discussion. I hope it will solve my problem too. I used openssl s_client -connect yourdomain.com:443 for an SSL checking which is getting from internet. Is my try is correct?
@Nitinkumar You should NOT follow the install instructions from nearly 8 years ago.
The current install for Certbot is here: https://certbot.eff.org
There are also other ACME Clients available: ACME Client Implementations - Let's Encrypt
If you explain more what problem you have we can help. Had you posted a new Help section topic you would have been shown the form below. Please answer as much as you can
==================================================
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.
