Please don't avoid posting the secondary config.  I can guess from 
above that your secondary config might say:

failover peer "primary" {

If that is the case, that won't work.  The failover peer name is a 
name describing the grouping of two failover entities, so it must be 
the same name on both servers.  Try changing both servers to use e.g.:

failover peer "failover1" {
