After setting up the Spectrum / eHealth integration the following error is seen when attempting to save the settings: SPC-EHI-10031: Invalid topology, please correct. The IP address for the eHealth topology on the Spectrum configuration page is


eHealth 6.3.x and Spectrum 9.x and 10.x


Configuring the integration against the eHealth system loopback


The integration will not work against the system loopback address ( You must configure the /etc/hosts file of the eHelath system so that the system resolves to the appropriate IP address. Here is an example:


 $ cat /etc/hosts       
 # Do not remove the following line, or various programs 
 # that require network functionality will fail. localhost.localdomain localhost
 ::1 localhost6.localdomain6 localhost6
 <System IP Address> <eHealth Host Short Name> <eHealth Host Long Name>
