Tasks do not reload after upgrade to Qlik Sense June 2018
 

2. Disable the loopback check

Reopen Registry and navigate to HKEY_LM\System\CCS\Control\LSA\MSV1.0 and create the following DWORD key 
DisableLoopbackCheck
Value : 1

3. Then, reboot the box

Hello @saso70 

Please review A specific task displays Error status message No worker scheduler found  for an additional root cause.

Should neither of the articles help, please post about your issue directly in our Qlik Sense Management and Deployment forum, including the version, information about your setup, and the errors you receive.

All the best,
Sonja

@saso70 Did you find a solution for your problem? I see the same error after upgrading

Ok, found it myself. Theres a new checkbox in the node settings called "Scheduler to do preloads", which must be enabled...
