Failed to send message to site pcap1. Error code is ORA-12521.It is not an issue with either password file, It having issues to establish connections with "prod1" ,
Have you configured static listener entry?
And What local_listener value you have set ?
From all instances
$lsnrctl status
12521, 00000, "TNS:listener does not currently know of instance requested in connect descriptor"
// *Cause:  The listener received a request to establish a connection to a
// database or other service. The connect descriptor received by the listener
// specified in addition to the service name an instance name for an instance
// (usually a database instance) that either has not yet dynamically registered
// with the listener or has not been statically configured for the listener.
// This may be a temporary condition such as after the listener has started,
// but before the database instance has registered with the listener.
// *Action:
//  - Wait a moment and try to connect a second time.
//  - Check which instances are currently known by the listener by executing:
//    lsnrctl services <listener name>
//  - Check that the INSTANCE_NAME parameter in the connect descriptor specifies
//    an instance name known by the listener.
//  - Check for an event in the listener.log file.
