Thanks. I've added the two lines to the ipsec.conf file and increased
debugging.  It appears to be the same error.

Here is the log from the left side and right side as well as the
strongswan.conf file.
You'll see in the logs that some certs are loaded but I am not using them
in my ipsec.conf.  I just want to use PSK's at this time.
