User receives the error message Wireless Location server unreachable when HTTPS is enabled


Core Issue

Whenever a user switches from an HTTP to HTTPS location, the server produces many Secure Sockets Layer (SSL) exceptions and potentially locks up.


This issue is documented in Cisco bug ID CSCsc69262.

The Cisco location appliance that is currently integrated into the wireless system stops responding correctly to the getserverinfo command, and the Server Events log in the Wireless Control System (WCS) server shows THROW events.
There are many events of messages from WCS under Location Server > Server Events.

The location appliance enhances the high-accuracy built-in WCS location capabilities by computing, collecting,and storing historical location data, which can be displayed in WCS. In this role, the location appliance acts as a server to a WCS server by collecting, storing, and passing on data from its associated controllers.

This issue is first found in version 2.0(31) and is first fixed in these versions:

  • 2.1(34)

  • 4.0(66)

  • 2.0(42)

As a workaround, disable HTTPS access between the location appliance and the
WCS by unchecking the box.

For more information, refer to the Downloading Software to Location Servers section of Performing Maintenance Operations.

For information on how to install the location version for full functionality, refer to the Comparison of WCS Base and WCS Location 700 section of Chapter 1 - Overview.
