Summary: This error may also occur if you forget the following line in your VirtualHost section:

SSLEngine on

Solution 2:

The problem ended up being in a different configuration file than the host that was listed in the error. It was due to the fact that there were duplicate ServerName values in two of the files. I fixed the wrong one and it started back up (bye bye that half an hour) :-) .

To troubleshoot this I disabled all the sites and then enabled a couple at a time until I ran into the problem again.
