I have configured the wso2 IDM as Key manager as per the documentation but getting the below error :

When I'm trying to access the API getting the below response on the API manager console.

<ams:fault xmlns:ams="http://wso2.org/apimanager/security"> <ams:code>900900</ams:code> <ams:message>Unclassified Authentication Failure</ams:message> <ams:description>Error while accessing backend services for API key validation</ams:description> </ams:fault>

  • Questions seeking debugging help ("**why isn't this code working?**") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it **in the question itself**. Questions without a **clear problem statement** are not useful to other readers. See: [How to create a Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve). – André Mar 27 '18 at 10:02
  • I'd recommend to check the URLs you've entered to the AM's api-manager. xml – gusto2 Mar 27 '18 at 11:11
  • Same reported in https://stackoverflow.com/questions/39217448/wso2-apim-2-0-clustering-deployment-issue-when-try-api-console-from-api-store – Pubci Mar 27 '18 at 11:30
  • I had checked that but its in the previous version , so I'm assuming its already fixed in the latest version 2.1.0 – user3868307 Mar 27 '18 at 12:24
