Qlik Sense Desktop: authentication errors out with Server authentication attempt failed

[Nao_Baba]

Authenticating Qlik Sense Desktop against Qlik Sense Enterprise on Windows fails with:

Server authentication attempt failed.

Resolution

To identify the correct root cause, test the connection from the Qlik Sense Desktop client machine to the server.

1. Open Windows PowerShell (as an administrator)
2. Run the following command to test the connection against the Qlik Sense Enterprise on Windows server using port 443:
   
   Test-NetConnection -ComputerName <hostname> -Port 443
   
   

Depending on the results:

• If the test connection succeeds, the possible cause is an Authentication URI misconfiguration.
• The response Name Resolution failed indicates an issue with the hostname resolution or points to the hostname being incorrect
• The response TCP connection failed indicates a connection issue between the Qlik Sense Desktop host and the Qlik Sense Enterprise on Windows Server. In this case, retest with an IP address instead of the server name.

Authentication URI misconfiguration

If the authentication URI is incorrect:

1. On the Qlik Sense Enterprise on Windows Server, open the Qlik Sense Management Console
2. Go to Virtual Proxies
3. Verify the Client authentication link host URI; make the required changes
   
   Example: Ensure the Prefix is included in the URI
   
   
   
   
4. Authenticate the Qlik Desktop client

Hostname resolution issues

Hostname resolution issues may be caused by network issues. Contact your network admin for details.

There are options available in the authentication link URI configuration as well:

1. On the Qlik Sense Enterprise on Windows Server, open the Qlik Sense Management Console
2. Go to Virtual Proxies
3. Verify that the Client authentication link host URI uses the correct name; if the name is correct, change it from hostname to an IP address
4. Authenticate the Qlik Desktop client

Environment

• Qlik Sense Enterprise on Windows (all versions)
