Avalon with fabric can't get work order result: [INFO __main__] Work order result None

[justalittlenoob]

Avalon: master branch
fabric: 1.4.4

When i deploy Avalon and Fabric on the same machine, it works well.
But when i deploy Avalon on machine A, Fabric on machine B, there will has the following issue.
Any advice would be appreciated.

1. start Fabric on machine B.
   cd $TCF_HOME
/scripts/start_fabric.sh -u

2. copy mywork from B to A.

3. start Avalon on machin A.
   docker-compose -f docker-compose.yaml -f docker-compose-sgx.yaml -f docker-compose-fabric.yaml up --build

4. run generic client inside avalon shell container on A
   docker exec -it avalon-shell bash
cd examples/apps/generic_client/
./fabric_generic_client.py -b fabric --workload_id "echo-result" --in_data "zHello" -o
