Requests Using Internet URL fail on LAN Access

Sorry but something when wonky when I cut and pasted the caldav directives
from the Nginx config file. Here is the correct entries as they appear in my
config file:

location = /.well-known/carddav {
        return 301 $scheme://$host/remote.php/dav;
    }
    location = /.well-known/caldav {
        return 301 $scheme://$host/remote.php/dav;
    }
