Troubleshooting: Check Point R80 - "CheckPoint API client error"

Symptom

TOS returns a Checkpoint API client error even though a status check on the Check Point R80 API server shows that it is running.

Check the Status of the Check Point API server

Run the following commands to display the status of the API server:

[<ADMIN> ~]#expert
[<ADMIN> ~]#api status

The output displays the following:

--------------------------------------------
Overall API Status: Started
--------------------------------------------
Test SUCCESSFUL. The server is up and ready to receive connections

Cause

You do not have permission to access /web_api/login on this server. You can verify the cause by looking at the following log files on the Tufin server:

/opt/tufin/logs/services/device-collector/securetrack.client.<device ip>_<mgmt_id>
