Connector for Microsoft Dynamics, "The endpoint associated with contract is not found"

Hi Experts,

I was setting up Demo System about integrating between Dynamics AX 2012 R3 and CRM 2016 using Dynamics Connector V3 CU4 (3.4)

I followed these docs here https://www.microsoft.com/en-us/download/details.aspx?id=10381 to set up configuration, my settings look like this 

Every connection is working fine.

here is AX 2012 Adapter configure

In AIF Inbound ports, I was setting up DynamicsConnectorDefaultServices service with operations like below, this service can be started as well.

I set up Maps in Connector like below

I tried to active Employee Service to ERP System User Map, but in logs session, It gave me errors"The endpoint associated with contract ":ConnEmployeesService" is not found."

I can not figure it out. AX has been done Compile and full CIL without errors, I also checked in AIF history had no coming message

Please share me your ideas, my appreciation.

Thank you
