AlwaysOn - Unable to connect to correct server with ApplicationIntent=READONLY

Question

Having issues trying to get the READONLY intent to work on our AlwaysOn setup.
SETUP is
Azure VM
NIS-SQL01
NIS-SQL02
They run with a AlwaysOn High Availability, this works fine, the AGL also works fine from outside the Azure environment. However when we try and define the connection to be READONLY, we are still getting the Primary Server when connecting.
running
select ar.replica_server_name
, ar.endpoint_url
, ar.replica_server_name
, ar.availability_mode_desc
, ar.failover_mode_desc
, ar.session_timeout
, ar.primary_role_allow_connections_desc
, ar.secondary_role_allow_connections_desc
, ar.backup_priority
, ar2.read_only_routing_url
from sys.availability_replicas ar
inner join sys.availability_read_only_routing_lists avr
on ar.replica_id = avr.replica_id
inner join sys.availability_replicas ar2
on avr.read_only_replica_id = ar2.replica_id

I can connect directly from one of the NIS-SQL servers to both of the read_only_routing_urls.
Made sure the Firewall settings allow for incomming connections on the specified ports.
I feel like i have tried almost everything that I could find through google, run through the MS Knowledge base step by step trying to find what might be wrong without any issues to the setup.
So hope that there might be some here who could shine some light or give som ideas on what I might be missing.

Hi,
I suspect you have read this article:
Use ReadIntent Routing with Azure AlwaysOn Availability Group Listener           
http://blogs.msdn.com/b/alwaysonpro/archive/2014/03/31/use-readintent-routing-with-azure-alwayson-availability-group-listener.aspx
Meanwhile, read-only clients must direct their connection requests to this listener, and the client's connection strings must specify the application intent as “read-only”. Make sure that you also specified the Application Intent=Read-only parameter in the
connection string.
Thanks.
