"HTTP-400 Bad Request / HTTP-409 Conflict" when connecting from Qlik Alerting to Qlik Sense

[Daniele_Purrone]

When trying to connect from Qlik Alerting to Qlik Sense during the first setup, the error "HTTP-400","title":"Invalid request.","detail":"Bad Request" is displayed.

The HAR file provides some more details:

{"error":[{"code":"HTTP-400","title":"Invalid request.","detail":"Bad Request"}],"errors":[{"code":"HTTP-409","title":"Conflict.","detail":"The request could not be completed due to a conflict with the current state of the target resource."}]}

Environment

• Qlik Alerting, November 2020

Resolutions

• The issue might be due to Qlik Alerting being installed on a Domain Controller. If so, please, install Qlik Alerting on a standard server.
• Make sure to have a license assigned to the user used by Qlik Alerting
• Upgrade to November 2020 SR1 or higher, since that includes improvements in the connection between Qlik Alerting and Qlik Sense
