As you proceed with configuration, it will be advised to fully configure the SPS master before making it master, then create their SPS cluster, and fully configure their SPP cluster, before joining SPP to SPS.
The solution was to perform the following steps:
1. Unjoin rejoin remainding SPS replica
2. Perform force unjoin of current sps joined it to it remove it
Blow away that sps and decide wiether to build that SPS as 6.1 or patch a 6.0
Build a 6.1 cluster
3. Install SSL certificaate on the SPP cluster
4. Join the new 6.1 cluster to the new SPP cluster.
