Cannot renew lets encrypt certificate on plesk

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. https://crt.sh/?q=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:stevenknoop.co.za

Getting the error below when trying to renew the SSL cert:

Hi,

The problem is on your server side.

Your https connection to https://www.stevenknoop.co.za/ is posing “(35) schannel: failed to receive handshake, SSL/TLS connection failed” (No matter what url visited)

Please check your ASP.net config or Plesk config.

Thank you

Thank you.

What do I need to check for?

Ensure your 443 vhost config contains enough for the TLS to run.

• protocols (TLSv1.2, etc.)
• ciphers
• certificate (private key and public key)

Hi

Yes it does. I have other sites on there whereby the SSL is working fine.
This was working but when I try and renew the cert, I get that error.

Please recheck the config - look for any typos or punctuation errors.
