The web interface for the pings service did not exist in BlueOS 1.0, and is currently only available in recent BlueOS-1.1 beta releases (which you can try out by selecting the desired version from the Version Chooser with Pirate Mode turned on). The “Available Services” page is generated from detected HTTP servers, so does not display services without an interface/API.
From a quick look, the service detects and successfully connects to your Ping360, then proceeds to wait for any other updates to the ports. The service itself does not seem to be aware of any issues.
This comment (and the thread preceding it) may provide some insight into possible causes for the problem you’re running into.
