Creating connectors in Qlik Sense got stuck in a spinning dialog

The Data Load Editor or Data Manager fails to create a new connector connection. The connection dialogue remains at the spinning icon and no progress is being made.

The relevant connector process (eg. QvRestConnector.exe) is idle in the Task Monitor.

One possible root cause is Antivirus on installed on the server. The inter-process communication between Qlik Engine and connector processes (for example QvODBCConnector.exe) is done via named pipes. In certain cases, Antivirus programs restrict named pipes, which blocks communication between Qlik Sense and connectors.

For example,  named pipes being blocked by McAfee Antivirus.

 

Resolution:

 

  1. Temporarily disable Antivirus on Qlik Sense server to see if the connectors work again
  2. Exclude AV scan from executable files of Qlik connectors (C:\Program Files\Common Files\Qlik\Custom Data)
  3. Configure Antivirus program, make sure named pipes are not blocked

 

 

Environment:

Qlik Sense Enterprise on Windows 
Qlik REST Connector 
Qlik Salesforce Connector 
Qlik ODBC Connector Package
