Hi @robb183  you should refer to the this article Configuring the Monitoring apps 

Also if you where using centralized logging in your Nov 2019 version this has been deprecated. You should ensure that is is disabled How-To-Enable-Disable-Centralized-Logging-Mode and configure the Monitoring app to use the Log files only.

Hello @robb183 ,

Kindly ensure the connection are well configured and if you are using a prefix for the windows authentication then that the connection are pointing to such.

Could you also add more rows of the error or the full task log if possible for further context?

Cheers,

Albert

Hi @Eugene_Sleator 

is it better to disable some services before performing the activity in your opinion?

Thanx

Hi @robb183  no you don't need to stop any services. But restart the Qlik Sense Repository Service(QRS) and the Qlik Sense Service Dispatcher(QSD) services after making changes.

Hello @robb183 ,

And is the DB on the central node or a dedicated node?

Cheers,

Albert

Hi @Albert_Candelario 

Central node.
I solved the problem by changing localhost with FQDN node  in the configuration parameters of all REST connections from the same app load task.

I followed the directions in this link
