Renewal attempt fails. "Incorrect validation certificate"

A while ago I installed certificates on a VPS that hosts several apache vhosts.

After receiving a notification that certificates were due to expire, I attempted to renew them.

I use this command:

‘letsencrypt-auto renew’

This returns:

ll renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/[name of vhost]/fullchain.pem (failure)

Towards the end of the error output is a a notice concerning a site that I used to host on this server and that I’ve since moved…


  • The following errors were reported by the server:

    Domain: []
    Type: unauthorized
    Detail: Incorrect validation certificate for TLS-SNI-01 challenge.
    from Received certificate containing

So my hypothesis is that records concerning this non-existent site are somehow preventing the renewal process to complete.

I’ve removed the apache vhost files and dissabled the site.

What else do I need to do in order to renew certificates for existing sites?
