Secondary Site Install Failure: ReadCertificateThumprint : Failed to get SSB certificate thumbprint

Question

I am having some issues installing a secondary site at a remote location and it’s driving me crazy. Here is the setup I have.
SCCM 2012 Primary Site in datacenter
SQL Server 2012 hosted on the primary site server
Firewall ports opened for 80, 135, 443, 445, 1433, 4022, 8530 on cisco and host firewalls
Attempting to have secondary site at each branch office
Secondary site server computer account is in local admin group on primary
Primary site server computer account is in local admin group on secondary
Secondary site server has full access to system management container in AD
Secondary site server computer account is in a security group which has sysadmin rights on the primary SQL Server
Utilizing Secondary Site Server pre-existing SQL 2008 R2 instance
Confirmed 1433, and 4022 accessibility with telnet from secondary to primary
I run the secondary site wizard from the console, it passes all prereqs and runs setup for about 5 minutes on the secondary site server and fails here (ConfigMgrSetup.log):
***Select dbo.fnConverBinaryToBase64String9thumbprint) FROM master.sys.certificates WHERE name='ConfigMgrEndpointCert"
CSControlSetup::ReadCertificateThumbprint : Failed to get SSB certificate thumbprint.
Error: Failed to setup SQL Server certificate for service broker "%NameOfMySecondarySiteServer%"
Error:Failed to initialize site control data.
I’ve searched around and the only thing I really saw was a reference to a local LSA password filter, which my secondary site server does not have.
Any ideas?
Thanks!

Update: I opened up all firewall ports between the two and still get the error.
