Clarity PPM On Premise

Issue/Introduction

After upgrading to Clarity 15.8, users are intermittently running into an Error 501 Not Implemented error on their home page. 

The environment has two servers, and after further review it appears to only happen when the users are logged in to one of the two servers. When they are on the other server is when everything works as expected with no errors. 

Environment

Release : 15.8

Component : CA PPM APPLICATION

Resolution

The Clarity cache will need to be flushed on the server with the problem. After doing this, the General page will display without error for the users. 

Additional Information

For steps on how to flush the Clarity cache, see KB98199
