Need help resetting pkg/server:default configuration to upgrade my system to an SRU.

I attempted to update my system to an SRU but it failed with

"Unable to contact valid package repository

Encountered the following error(s):

Unable to contact any configured publishers.

This is likely a network configuration problem.

http protocol error: code: 503 reason: Service Unavailable

URL: 'http://pkg.oracle.com/solaris/support'"

My pkg/server:default service is currently in maintenance citing "/var/cache/pkg/sysrepo' does not contain a valid package repository."  I have tried different paths to no avail.  My zone_proxyd and system-repository:default are also down.

My certificates and key files are up to date, but I believe something is missing in configuration.  My publisher is online and can see available SRU's.

[root@spechost:pkg]# pkg publisher

PUBLISHER                   TYPE     STATUS P LOCATION

solaris                     origin   online F https://pkg.oracle.com/solaris/support/

Any ideas on what I can do to find a proper repository on the system?
