My domain

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

Error: Could not issue a Let’s Encrypt SSL/TLS certificate for Authorization for the domain failed.
Invalid response from
Type: urn:acme:error:connection
Status: 400
Detail: Fetching Connection reset by peer

The operating system my web server runs on is (include version):win2012

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):no, only powershell

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):plesk


The problem is on your server side.

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

Please check your 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)


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.
