Troubleshooting - Managing QMC resources

This section describes problems that can occur when managing QMC resources.

Error message: 400 Bad Request

There is more than one possible cause when the error message 400 Bad Request is displayed.

Importing an app in the QMC fails

The logs show an error message: Server:ImportApp_impl caught extended exception 400: Bad Request

Possible cause  

The app contains a web connection that makes the URL exceed 1024 characters.

Proposed action  

1. Open the app in Qlik Sense Desktop to see if the app contains a web connection that makes the URL longer than 1024 characters.
2. Use a service, such as bit.ly to shorten the URL.

The REST HTTP request incorrect

Possible cause  

The REST HTTP request to the proxy or the repository is incorrectly formatted.

Proposed action  

Correct the formatting of the REST HTTP request.

Error message: 403 Forbidden

Possible cause  

• There are too many root certificates on the computer (> ~300), and as a consequence, the Qlik Senseservices are not allowed to communicate.
• You are trying to access a resource that you are not granted access to, according to the rule engine in the repository.

Proposed action  

Remove any unused root certificates. See also the following Microsoft help documentation:

Clients cannot make connections if you require client certificates on a Web site or if you use IAS in Windows Server 2003

SSL/TLS communication problems after you install KB 931125

Error message: 405 Method not allowed

Possible cause  

The URL refers to a non-existent REST function.

Proposed action  

Modify the URL.

Error message: Internal server error 500

Possible cause  

An unidentified error has occurred.

Proposed action  

Check the system log files at the following locations:

• %ProgramData%\Qlik\Sense\Log\Proxy
• %ProgramData%\Qlik\Sense\Log\Repository

The start page displays a number next to Engine, Repository, Proxy, or Scheduler

Possible cause  

The service is down.

Proposed action  

Check the log file at this location: %ProgramData%\Qlik\Sense\Log\<Service>.

I do not know the name of a mandatory SAML attribute

Possible cause  

The name of a mandatory attribute, (userID, userDirectory, or an added mandatory attribute) is not available.

Proposed action  

Do the following:

1. Type an arbitrary name as the attribute name.

2. Make an authentication attempt.

   The attempt will fail because the attribute name is incorrect.

3. In the Proxy Audit log, find the row that contains "Existing SAML attributes:".

   You will find the name or friendlyName and Value of all available attributes.

4. Find the name of attribute that you want to use and use that name instead of the arbitrary name that you originally entered.

The following are examples of what you can find in the log:

Existing SAML attributes: [Name='uid', Value='jod'] [Name='givenName', Value='John'] [Name='sn', Value='Davidson'] [Name='cn', Value='John Davidson'] [Name='mail', Value='john.davidson@domain.com']

Reload is not working

I clicked Reload now on an app but the reload is not working.

Possible cause  

The task status is not Success.

Proposed action  

Check the log file at this location: %ProgramData%\Qlik\Sense\Log\Script.

A task is not executed

Possible cause  

The task status is not Success.

Proposed action  

On the tasks overview page in the QMC, click ] in the status column to display a summary of the execution steps.

You can also check the log file at this location: %ProgramData%\Qlik\Sense\Log\Scheduler.

I cannot change the properties of a user

Possible cause  

User properties imported from Active Directory (AD) cannot be changed in the QMC.

Proposed action  

Change the property in AD and sync again.

See: Synchronizing with user directories

The user sync is not working

• I cannot synchronize users when clicking Sync all selected user directories in the User directory connectors overview.
• A scheduled user synchronization task is unsuccessful.

The UDC is not configured

Possible cause  

The user directory connector is not Configured.

Proposed action  

Make sure that the User directory name is unique and not blank.

The UDC is not operational

Possible cause  

The user directory connector is not Operational.

Proposed action  

Check the UserManagement_Repository log at this location: %ProgramData%\Qlik\Sense\Log\Repository\Trace.If you remove the source file that a user directory connector is based on, it will not be operational.

The UDC property Page size of search value is incorrect

Possible cause  

The user directory connector property Page size of search is incorrect.

Proposed action  

Set the user directory connector property Page size of search to no value.

A node in a multi-node environment is not getting online

I have recreated a node in the QMC (created, deleted, and then created it again) but the node is not getting online. There is a warning message in the log: “Node disabled (most probable cause is having been unregistered from a cluster). Aborting startup...”.

Possible cause  

Deleted nodes are not allowed to be restarted and reused in a multi-node environment.

Proposed action  

Do the following:

1. Delete the node in the QMC.

2. Uninstall the software from the node.

   See: Uninstalling Qlik Sense

3. Reinstall the software on the node.

4. Create the node again in the QMC.

I cannot import an extension

Possible cause  

• The extension is not zipped.
• The compressed file has the wrong format.
• The zip file contains invalid files.
• The extension password is incorrect.
• The extension is a duplicate of an already existing extension.

Proposed action  

• Make sure the extension file is correctly zipped. You cannot use any other file format for compression than .zip.

• Make sure that the zip file only contains relevant extension files.

• Edit the extension so that it is not a duplicate.

I cannot migrate an app

I cannot migrate an app despite several attempts.

Possible cause  

The app is corrupted.

Proposed action  

Check the app migration log files for information that could explain the failure. The log files are available at this location: %ProgramData%\Qlik\Sense\Log\.

I want to change the default user account

I want to change the default Windows user account, that is used to run Qlik Sense.

Proposed action  

Modify the Qlik Sense installation.

Do the following:

1. Open the Control Panel and select Uninstall a program.

2. Select Qlik Sense from the list of programs and click Change.

3. Select Modify in the Qlik Sense setup dialog.

The Windows user account can also be changed manually. This is done by modifying the user account that is used to run the Qlik Sense services and the user account that is used to access the folder where the Qlik Sense logs are stored. The default path to the Qlik Sense log folder is %ProgramData%\Qlik\Sense\Log\<Service>.

An imported file is recreated after deleting it from the local file system

I am using Internet Explorer and after importing an app or an extension in the QMC and removing it from the file system, the file is recreated but cannot be opened, moved, or permanently deleted.

Possible cause  

The file did not close properly after being imported.

Proposed action  

Close Internet Explorer and open the QMC again. The locked file should no longer be visible.
