duplicate target database from active database fails with RMAN-04006: error from auxiliary database:

Hi,
I'm attempting to clone a target database to auxillary database.  I'm following the documentation and they mention it's because i don't have a STATIC listerner define.  I verified on my auxillary server that my listener has the SID.

(SID_DESC =
      (GLOBAL_DBNAME = HULK)
      (ORACLE_HOME = /u01/app/oracle/product/11202)
      (SID_NAME = HULK)
    )


What is the difference between a static listener and nonstatic?
Doing a listener status shows the SID is UNKNOWN and BLOCK.

Service "HULK" has 1 instance(s).
  Instance "HULK", status UNKNOWN, has 1 handler(s) for this service...
Service "HULK.main.sjcd.edu" has 1 instance(s).
  Instance "HULK", status BLOCKED, has 1 handler(s) for this service...
