QmcTaskTableCacheDisabled error in Qlik Sense Enterprise on Windows

[FabioSanchesRibeiro]

Qlik Sense Enterprise on Windows frequently logs the following error:

Error: QmcTaskTableCacheDisabled 

The solution documented in Tasks in the Qlik Sense Management Console don't update to show the correct status after an upgrade has been implemented successfully, but the error continues to be logged.

Resolution

Clearing the browser cache will resolve the issue temporarily. To more permanently make certain the cache is updated:

1. Add additional response headers to the Qlik Sense Virtual Proxy:
   

   Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
   Cache-Control: no-cache, no-store, must-revalidate

   For more information about configuring response headers, see How to add additional response headers in Qlik Sense.
   
   The additional headers implement a feature which checks if the cache is up to date, prompting the browser to make a new request using the correct data for each accessed version.
   
   
2. Clear the browser cache

Cause

Browser cache. Clearing it will temporarily resolve the issue.

Thank You Sonja,

      The solution seems works just for SSL with certificate VP access.  On two customers I had issues in accessing both QMC and hub using the IP or internal name of the server.
