F5 Rest Giving 404 error

I am trying to get all pool members from the f5 rest API. I a saw this document: https://devcentral.f5.com/wiki/iControlREST.APIRef_tm_ltm_pool_members.ashx

so I would assume I could hit this url: https://dplb02.mgt.sv5.nskope.net/mgmt/tm/ltm/pool/members

however I get a 404 error, how can I get all pool members?

Traceback (most recent call last):
File "", line 1, in 
File "bigip/ltm.py", line 61, in members
    return self._get('/mgmt/tm/ltm/pool/members')
File "bigip/ltm.py", line 41, in _get
 raise HttpError("Host: {0} Code: {1}".format(url, response.status_code))
bigip.ltm.HttpError: Host: https://dplb02.mgt.sv5.nskope.net/mgmt/tm/ltm/pool/members Code: 404
