If Owl v4 statistics graphs are not loading for one or more servers in the WebUI, this is almost always caused by one of the following two issues.
Common Causes
-
Hostname mismatch: The server hostname does not match what cPFence expects. Owl relies on consistent hostnames to collect and display statistics correctly.
-
Passwordless SSH is not configured correctly: The main control panel must be able to connect to the affected server via SSH without a password. If SSH access fails or prompts for a password, Owl cannot collect data.
How to Fix
-
Verify that the server hostname is set correctly and matches the expected value. You can follow the hostname setup guidance below:
How to set up the correct hostname -
Confirm that passwordless SSH from the main control panel to the affected server is working as expected.
-
Once both are confirmed, restart the WebUI:
cpfence --restart-webui
After restarting the WebUI, allow a few minutes for Owl v4 data to start populating again.
