We are using a 3 member CPPM Cluster, geographically separated. The #2 CPPM is the publisher, #1 & #3 are subscribers. When a guest that points to #1 CPPM for registration, they are presented with the registration page but when they click Submit, they receive a message stating:
"Received Request From Unknown Subscriber"
and the registration page just stays there.
When I point them to the #2 CPPM (Publisher), the registration works properly.
I am under the impression that subscribers can handle Guest Registrations and they pass the information to the Publisher. Is this not the case, or do I have something else wrong?
I am not sure what information I should provide for troubleshooting, please let me know.
UPDATE: Also I notice that when I go to the Guest Manager of the Subscriber node and click on Manage Accounts, I get that exact same message. I tried removing the subscriber from the Cluster and re-adding it, but that did not work. I am also seeing this exact same issue on the #3 subscriber, so it is not isolated to just the #2 server.
