Solution:

1. Check whether the HSF services are in the same VPC and region. If not, they cannot be connected.
2. Check whether the HSF services are in the same security group. If not, enable port 12200.
3. Run telnet 10.10.1.1 12200 to check whether the port can be connected. If not, check the firewall configuration of the instance with the IP address 10.10.1.1.
