The Qlik Web Connectors November 2017 Release (2.28.2) is now available on the Qlik.com download page‌ (you need to be logged in to Qlik.com)

Along with a number of general improvements, this version has 4 new beta connectors added to the suite including:

  • Office 365 Mail/Contacts/Calendar
  • OneDrive v2 - which is enabled for OneDrive business accounts,
  • IBM Watson Natural Language Understanding for more text and sentiment analytics, and
  • for all of you desperate to better your fitness performance, there's even a Strava Connector

This now means that there are 47 connectors available

If you're using Qlik Web Connectors 2.2.0 and either any beta connectors or standard connectors, please read the note towards the end of this post about upgrading.

In this release no connectors were moved from a beta state to either Premium or Standard Connectors.

Some multi-source connectors have been split into individual connector, so for example in previous versions of the Qlik Web Connectors we had the Premium Qlik Sentiment and Text Analytics Connector, which required a subscription and corresponding LEF.

You will now see the following Premium Connectors listed, although they all share the same, single

Sentiment & Text Analytics subscription and LEF entry:

  • Qlik MeaningCloud Connector
  • Qlik Repustate Connector
  • Qlik Sentiment140 Connector

The Qlik RegEx Connector is now a free, Standard Connector

The following connectors have been split out but also deprecated:

  • Qlik Alchemy Connector
    • This has been replaced by the Qlik Watson Natural Language Understanding Connector
  • Qlik Saplo Connector

Other connectors that have been split out are the AYLIEN Connector and Mailbox Connector.

The Qlik script that has been generated using these previous connectors may need to be modified. Please refer to the Release Notes, for more information.

Current Users of Beta Connectors or Only Standard Connectors

As a reminder, if you are using Qlik Web Connectors 2.2.0 and either:

  • any Beta Connectors or
  • any Standard Connectors WITHOUT any Premium Connectors enabled

then these will expire on 31-Jan-2018, so you must upgrade to the new November 2017 Release (2.28.2) version as soon as possible.

The new expiry date in the November 2017 Release will be 30-Nov-2018.We also maintain a schedule here.

See here‌‌ for help on upgrading.

Please see the release notes, also on the download site, for full details.

Oh dear, I cannot get the new version of the Qlik Notification Connector to work.

I have been using the old version Qlik Notification Connector to send emails and this has been working & stable for quite some time.  So all the smtp relay stuff is working fine

But this new version comes up with this error.

I've tried everything I can think and can't find any useful clues in any log files.  We are not using SSL, but have tried all 3 SSL modes just in case.

Anybody got any suggestions ?


Hi Bill,

I think that we need to take a closer look at this.

I've sent you a 'connection' request through this community - if you can accept and then request my connection/follow, then I will DM you with my contact details so that we can get a bit more hands on with this issue.

Thanks for your patience,




I'm new to the Web Connectors users, We use Windows Server 2008 R2, .net 4.7.1 but Web Connectors 2.2 does not start as a Windows service. It only works when running as application.

There is an issue when starting it as a service - it does not start, Applications log has the follow message:


Impossible to start the service. System.InvalidOperationException: Unable to configure namespace reservation

   at QlikWebConnectorsService.Service.OnStart(String[] args)

   at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)


("Impossible to start the service" is a translation of Russian wording, not sure it's the same in English version)

and there are the following errors in the "Service_Startup_Log.txt" file (located in Web Connectors root folder):


11.01.2018 11:04:04 System.InvalidOperationException: Unable to configure namespace reservation

   в Nancy.Hosting.Self.NancyHost.StartListener()

   в Nancy.Hosting.Self.NancyHost.Start()

   в QlikWebConnectors.WebBootstrap.StartSelfHost()

11.01.2018 11:04:04 OnStart:ERROR: System.InvalidOperationException: Unable to configure namespace reservation

   в Nancy.Hosting.Self.NancyHost.StartListener()

   в Nancy.Hosting.Self.NancyHost.Start()

   в QlikWebConnectors.WebBootstrap.StartSelfHost()

   в QlikWebConnectors.WebBootstrap.StartSpecificVersion(Boolean isService)

   в APIConnectorEngine.Qwc.BaseBootstrap.Start(Boolean isService)

   в APIConnectorEngine.Qwc.BaseBootstrap.StartServiceVersion()

   в QlikWebConnectorsService.Service.OnStart(String[] args)


What is going wrong? How to fix this? Any thoughts are welcome...

Thanking you in advance.

Best regards,




I accepted your Connection Request.

I have also lodged Support Case 01301831 with Qlik, who have reproduced the issue with google smtp server but strangely only in the first attempt. They have reported this as a bug to Qlik R&D and acknowledged that this looks like a degrade.

It would be great if you could assist them [me] in any way you can.

In the absence of a fix it would be helpful if the previous Notification Connector could continue working for non licenced users beyond the end of the month.  We use this extensively in place of QlikView alerts.


Hi Maxim I think you need to check your URL reservations using netsh - some info here Troubleshooting Qlik Web Connectors installation ‒ Qlik Connectors

...if that does not help you could also try updating the service 'Log On' account to a specific account which has full read/write access to the directory under which QWC is running (the default value here will usually be a local system account which may not have the correct permissions).

See the properties dialog for the QWC service, some details here http://wiki.qvsource.com/Running-QVSource-Under-A-Standard-User-Account.ashx‌ (which needs to be included in the new help pages).


Please check that the service account admin permission / is a member of Administrators - this should resolve the issue with 'Unable to configure namespace reservation' for a Windows service.
