Article summary

When using the "Test Popups" feature within Pharos Administrator, the following error message displays: "Failed to connect to host localhost on port 28203"


When the Pharos Administrator can't connect to a Pharos Pop Up server, this error message might be displayed. Possible resolution as follows,

1. Open Windows Services and check whether the "Pharos Popup Server" is running.

NOTE: If  the Pharos Popup Server does not appear in Windows Services, it will need to be installed.

2. If there is a firewall running on the Pharos Server, make sure that "PopupSrv.exe" is in the exceptions list and the port 28203 is open.
