An error occurred or Failed to load connection error message in Qlik Sense - Server Has No Internet

Andre_Sostizzo — Thu, 25 Jun 2026 08:38:41 GMT

Changes must be made to all Qlik servers that will not be provided with internet access.

For servers not connected to the internet, they may be prompted with a pop-up error when browsing in the Hub or in the Data Load Editor with the following errors:

The Hub has continuous bubbles while loading forever
The Hub is stuck on the initial loading bar

Resolution

Only deploy of the listed options.

Option 1 will persist through upgrades, whereas Option 2 would have to be reapplied after every Qlik Sense Enterprise on Windows upgrade.

Option 1:

Stop all Qlik Sense services on all nodes
Edit C:\Windows\Microsoft.NET\Framework64\v4.0.30319\config\machine.config
1. If there is an empty <runtime/> tag, change it to
```
<runtime>     
     <generatePublisherEvidence enabled="false"/>  
</runtime>
```
2. If there is no <runtime/> tag, add the below anywhere above the closing </configuration> tag.
```
<runtime>
    <generatePublisherEvidence enabled="false"/> 
</runtime>
```
3. If the <runtime> section has existing content, add generatePublisherEvidence.
```
<runtime>
  <some other key="value"/>
  <generatePublisherEvidence enabled="false"/>
</runtime>
```
  Example:
Save the machine.config
Repeat on all nodes (if applicable)
Start services on all nodes

Option 2:

Stop all services on all nodes
Open C:\Program Files\Common Files\Qlik\Custom Data\QvRestConnector\QvRestConnector.exe.config in an admin level Notepad window
1. If there is an empty <runtime/> tag, change it to
  <runtime> <generatePublisherEvidence enabled="false"/> </runtime>
2. If there is no <runtime/> tag, add the below anywhere above the closing </configuration> tag.
  <runtime> <generatePublisherEvidence enabled="false"/> </runtime>
3. If the <runtime> section has existing content, add generatePublisherEvidence.
  <runtime> <some other key="value"/> <generatePublisherEvidence enabled="false"/> </runtime>
4. Repeat on all nodes and repeat for all .config files
- C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\QvOdbcConnectorPackage.exe.config
- C:\Program Files\Common Files\Qlik\Custom Data\QvSalesforceConnector\QvSalesforceConnector.exe.config
- C:\Program Files\Common Files\Qlik\Custom Data\QvEssbaseConnector
- C:\Program Files\Common Files\Qlik\Custom Data\QvRestConnector
- C:\Program Files\Common Files\Qlik\Custom Data\QvWebStorageProviderConnectorPackage
Start all services on all nodes
Validate

It may be necessary to include the key immediately before the runtime closing tag if there are many values in the runtime section.

HI, I have the same error, in the 'Data Load Editor', the data connections it's just a spinning wheel that never seems to stop. We are with Qlik Sense 2020 Sept Patch 7. The server machine has internet connections. The option 1 was applied without success. The option 2 was applied without success. Any tips will be appreciated.

Option 1 did not work.
Option 2 afterwards did not work, still incredible slow ...
do you need to do the same for the SAP-Connector configs, if installed?

Having the same problem, we're with May 2021 Release Patch 3.

@Gabriel_Araya we're you able to fix your issue?

@eclutario make sure you don't have error(s) in the network tab in your browser dev tools. I had an "unknown error" showing up despite I had apply the options listed in this article. I also had an error in the engine logs:

RestClient: HTTP request for url v1/connectors?xrfkey=ichBinEinBerlinR failed with error code 12175 (source: 5)

This solution did the trick for me (Qlik support provided it to me):

https://community.qlik.com/t5/Knowledge-Base/Qlik-Sense-Data-Load-Editor-quot-Unknown-Error-quot-Source-5/ta-p/1717301?_ga=2.266263181.343844665.1626168876-768955529.1623675039

Hope this helps!

Seems like I was finally able to fix the problem.

Problem was that it always took 1minute until data connections were loaded, both when entering script editor for the first time during a session and at random points afterwards.

What helped to identify the underlying problem was debug-view in Chrome ( Press F12). In that view an error for the Data Market showed up each time the connections finished loading.

Solution was to remove Data Market folder from C:\Program Files\Common Files\Qlik\Custom Data\

So if your server can't access the internet, I would recommend you remove that connector (and repeat that after each update).
Would be great if Qlik fixed this behavior, so the manual solution is no longer necessary in the future.

Hello @jaishree_Qlik

I would recommend posting about this issue directly in our community forum (Qlik Sense Deployment and Management), as that way you can make use of our active member base as well as our engineers monitoring the forums.

When posting on the forum please be specific and include screenshots of the error, mention your version, and give details about what you located in the logs.

Though to get you started: If you are seeing an error in your log files and have traced it back to the issue, I would recommend searching for the specific error in our knowledge base. If you are looking for a list of required ports overall, you can check your version of Qlik Sense on the help site. Here is a link to August 2022's version: ports.

You may also want to check out Data Connections Pane in Qlik Sense Hub not loading.

Another thing to consider is whether or not you have any custom security rules in your Qlik Sense environment which may prevent access to the Data Editor.

All the best,
Sonja

Dear

After upgrading to Qliksense May 2025 patch 5,

the default value is showing below under runtime tag for

- QvWebStorageProviderConnectorPackage.exe

And QvOdbcConnectorPackage.exe does not have runtime tag in the file
