Use the steps below to troubleshoot the Content Delivery Network (CDN) access error in Nintex Apps.

Issue

The following error may appear in the browser console, for example as a JavaScript error, or in the Salesforce Developer Console as a managed package exception:

  • Unable to connect to the Nintex Apps Core CDN:

Cause

This error indicates that the page is unable to load required resources from the CDN. Possible causes include:

  • Network connectivity issues:

    • Internet connection issues.

    • Corporate firewall that blocks CDN access.

    • Network proxy configuration issues.

  • CDN infrastructure issues:

    • CDN servers are temporarily unavailable.

    • High latency or service disruption.

Resolution

Use the following steps to resolve the CDN access error:

  • Check network connectivity:

    • Ensure the internet connection is stable.

    • Confirm that firewall or proxy settings are not blocking access to the Nintex Apps CDN domain.

  • If using Nintex Apps for Salesforce, disable CDN usage so that resources load directly from Salesforce static resources:

    1. Go to Settings > Org Preferences.

    2. In the CDN pane, turn off the toggle for CDN.
