Trouble adding 2nd vpn

So I am attempting to add a 2nd vpn to my existing setup and for some reason
I can't seem to get it to work quite right.

The issue I'm having right now is successful execution of the tinc-up
script.  It's probably something obvious but after several days I still
don't see what I'm missing.  I can see in syslog that
"Script tinc-up exited with non-zero status 1"

Both vpns are definitely running.

Following is some relevant console output.
