App Reload Fail With "Error: QlikView Connector is not responding" Or "Connector is not responding".

Scenario:

Qlik Sense has restricted, slow or no internet connection.
App reload fails with error message "QlikView Connector is not responding" or "Connector is not responding".
Sheets are slow to open.
ErrorCode.11041 occurs when opening up an App
ErrorCode.11043 occurs when creating a Database connection in the data load editor.

Cause:

Qlik connectors are cryptographically signed for authenticity verification. The .NET framework verification procedure used for this signing includes checking OCSP and Certificate Revocation List information, which are fetched from a online resource if the system doesn't have a cached local copy. These requests will timeout due to lack of access to online resource in environments with restricted, slow or no internet connection. Due to authenticity check failure the connector will not run, and the app reload fails.

Qlik R&D is evaluating options to mitigate the effect of restricted, slow or no internet connection for future releases of Qlik Sense.

Resolution:

This issue can be resolved by disabling the online dependency for .NET framework based authenticity verification.

There are two (2) ways of accomplishing this, either by modifying the configuration file for each connector or by changing the .Net Framework's machine.config file on a global level which applies for all connectors.

Option 1: Editing the Connector configuration file:Stop all Qlik Sense services on all nodes

Open the config file in the connector folder in C:\Program Files\Common Files\Qlik\Custom Data\
for instance C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\QvOdbcConnectorPackage.exe.config
Add the following values before the closing </configuration> tag:

<runtime>
<generatePublisherEvidence enabled="false"/>
</runtime>
Repeat steps 2 and 3 for all nodes and all .config files
- C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\QvOdbcConnectorPackage.exe.config
- C:\Program Files\Common Files\Qlik\Custom Data\QvDataMarketConnector\QvDataMarketConnector.exe.config
- C:\Program Files\Common Files\Qlik\Custom Data\QvSalesforceConnector\QvSalesforceConnector.exe.config
- C:\Program Files\Common Files\Qlik\Custom Data\QvRestConnector\QvRestConnector.exe.config

Option 2: Editing the .Net Framework's machine.config file

Edit C:\Windows\Microsoft.NET\Framework64\v4.0.30319\config\machine.config
1. If there is a <runtime/> tag, change it to
  
  <runtime>
  <generatePublisherEvidence enabled="false"/>
  </runtime>
2. If there is other stuff in the <runtime> section, then change it to look like this:
  
  <runtime>
  <some other="stuff">
  <...>
  <generatePublisherEvidence enabled="false"/>
  </runtime>
Save machine.config
Repeat on all nodes (if applicable)

NOTE1: Changes to machine.config affects all software using the .NET framework feature.
NOTE2: 3rd party connectors might be compiled for 32-bit platforms. In such case repeat steps above for the 32-bit version of the machine.config file; Path C:\Windows\Microsoft.NET\Framework\v4.0.30319\config\machine.config
