RP4VM - Added 3rd Appliance getting volume access errors

I added a 3rd vRPA appliance to each side of my cluster (version 5.1), and I have a lot of errors reported that are similar to this one below.

User volume [GROUP8_DFS, GROUP8_DFS.CERA, CG_RSET_ceradfs1_0_0_scsi] cannot be accessed by: RPA 3

I deployed the OVF just like I did the other 2, and ran the deployment manager to add a vRPA to vRPA cluster. Everything worked just fine, it has the proper IP addresses assigned, but I cannot get any traffic through it. I have set CG's to use that RPA, but my netflow shows no WAN traffic. I have rebooted all appliances, but the errors remain. I have also tried moving it to different ESXi hosts. Am I missing a step somewhere? Any help would be appreciated.
