Qlik Talend: What to do if you receive a 'We couldn't load the application' error when accessing the Talend Management Console

[Sonja_Bauernfeind]

Hello Qlik Talend admins!

We introduced a new Content Delivery Network (CDN) URL to support the Talend Management Console UI. This change was previously communicated in the product and can be found as an item in our release notes from R2026-01. 

Should you encounter the error We couldn't load the application when accessing your Talend Management Console, check with your network team to verify that the new CDN was added to any firewall exceptions.

• The change required: Allow https://cdn.cloud.talend.com
• Traffic Type: Client-side only
  • The URL is fetched by the user's web browser.
  • No changes are required for backend connectivity (Remote Engines and Clusters).

For all the required allowlist URLs, see Adding URLs to your proxy and firewall allowlist.

A relevant support article is available at Qlik Talend Management Console Error loading: We couldn't load the application.

If you have questions about this change, contact your CSM (Customer Success Manager) or the Support team.

Thank you for choosing Qlik,
Qlik Support
