Cannot start Qlikview Web Server Service

[Sonja_Bauernfeind]

QlikView Web Server service fails to start. Restarting the operating system does not resolve the issue.

The Web Server logs read:

QlikViewWebServer Service cannot be started. System.Net.HttpListenerException (0x80004005): The parameter is incorrect.
at System.Net.HttpListener.AddAllPrefixes()
at System.Net.HttpListener. Start()

at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

Resolution:

• Ensure that port 4750 is available and that no firewall or other security software is preventing the Web Server from binding to the port.
• Re-create the Config.xml file in the %ProgramData%\QlikTech\WebServer directory.
  • Rename or move config.xml which is on directory.
  • Start QlikView Web Server service from Windows service console.

Cause:

Possible root causes include a malformed config.xml or firewalls blocking the required Web Server port (4750) from binding.
