The certificate chain failed OpenSSL verification error

I recently took control of a website that was hacked and blacklisted by Google. I've cleaned up the site and gotten that domain unblacklisted, but AutoSSL is generating the following errors in the log:
Checking websites for “########” …

I've tried going through my VPS hosting company for support but they keep telling me I have to buy one of their SSLs which I'm pretty sure is BS because AutoSSL is working just fine for the other 30 websites on the server.

To clarify the issue, AutoSSL is generating an untrusted self-signed certificate for this site whereas the other sites are generating a trusted certificate with the certification path COMODO SECUREtm > cPanel, Inc. Certification Authority > [my website]

Hi @csidev

I was going to mention to you that based on that output it looked like the SSL request was successful. I"m glad the issue has resolved itself at this time though, thank you for following up. More than likely the delay was in issuing the certificate as Google's safe browsing is something Comodo looks at before issuing certificates.
