Autossl: Certificate available but not installing

Sorry if this is answered before, I searched but did not find this exact problem (but I'm probably not the first ;)).

I enabled autossl and run the cronjobs.

When I run the 5 minute cronjob manually I get:

Polling for “xxxxxx”’s new certificate for “” (order item ID “12707207”) …
The certificate is available. The system will now attempt to install it.
Certificate verification failed!
Certificate verified:
stdin: C = GB, ST = Greater Manchester, L = Salford, O = COMODO CA Limited, CN = COMODO RSA Certification Authority
error 20 at 2 depth lookup:unable to get local issuer certificate

So its available but the verification failed?
What does that mean?
Is this something on my system I can solve?

Edit: This goes for all domains on this server.

Someone told me a ca bundle is missing?
That shouldn't happen because the AutoSSL feature automatically generates the required certificate files. Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

Thank you.
