Aggregator failed to establish callback for device, not able connect to Thingworx composer

Question

Hello, 
 
I had already read and tried the thread " Trouble when trying to connect OPC Aggregator to ThingWorx Composer"
before writing. 
in the OPC aggregator, I had configured
HOST: 127.0.0.1
Port: 80
/Thingworx/WS
application key from thingworx expiry in 2020-10-21.
 
I did a testing, if I am using the OPC client from the aggregator and the communication is ok, I can read/write the value of the device. 
 
When I do a discover in the Industrial connection, I am able to see the tags from the device, and able to bind the tags from the devices to the thing. 
 
BUT, the connection seems to be down always, and when I check the log. it show unable to establish callback for device in the OPC aggregator. 
 
At the Thingworx, the Thing show "connected" but the bind data is showing "?".
 
I am not sure where is I should check now, can anyone give me any hint, I will go try it out.
 
Thank you in advance.

ps: let me know what additional info is required.
