Appliance cannot be reached (displays as “No registered Appliances found”)

After installing Forcepoint Security Appliance Manager (FSAM), a warning displays, saying that no registered Appliances are found. To resolve this issue:

Steps

Verify that the FSM server can reach the appliance in question.
  1. Use the Curl command (execute from a Linux machine that can reach FSM):
    curl -ik -X GET -u admin 'https://<triton IP>:9443/api/app/v1/appliances/
<appliance IP>/sys'
  2. Capture data coming in on the API port:
    tcpdump -nni eth0 tcp port 443
  3. Look at uwsgi logs on unreachable appliance:
    /var/log/appliance/uwsgi.log
  4. Verify API calls coming in.
