2. Verify that the LEDM endpoints are hosted by the device. Open the HPWSProxyService.log file,
which is available in the same location as the HP Device Proxy Console App provided in issue 1.
Find entries that contain the endpoint verbiage, such as the following:
Hosted Endpoints are
https://IPAdress:8022/434E434A-3230-3030-3735-2C768A3EB978
http://IPAdress:8023/434E434A-3230-3030-3735-2C768A3EB978/transfer
3. If no Hosted Endpoints are listed in the log file, check for errors, such as the following:
Exception caught in the function OnReceiveRequest...Object reference
not set to an instance of an object.
If this error is listed, the proxy agent cannot connect to the printer. It is likely that another
application is using the socket connection that HP WS Proxy Agent needs. This might mean that
VMware Workstation is installed on the same client as HP WS Proxy Agent.
4. Verify that the latest version of HP WS Pro Proxy Agent is installed. The version is displayed in the
Name and Version columns in Control Panel > Program and Features. Versions prior to HP WS
Pro Proxy Agent 10.3.1 display only the version in the Version column or might not display any
version at all.
DISCOVERY LOGS
Additional log file functionality that allows administrators to understand and troubleshoot PC-
connected device discoveries is available in HP Web Jetadmin. The following sections provide
instructions for enabling and gathering the logging details for HP SNMP Proxy Agent, HP WS Pro
Proxy Agent, and WMI.
