You may receive this error in Notifier.out when starting AlarmNotifier in Spectrum: Location service on <oneclickhostname> failed to connect: Not listening on port 0x50. check that the server is started and ready.
The main cause of the error is that AlarmNotifier is trying to connect to location service on Oneclick. In this scenario Spectrum and Oneclick are on two different servers. To resolve the issue, make sure that the Oneclick hostname and port are not entered under Spectrum Control panel -> Location server -> Client Applications.
These configurations are mainly used for the following purposes:
Hostname: Specifies the client application main location server hostname. It preserves landscape map integrity for different environments. Port: Specifies the client application main location server port.
