Error "Error: Internal error testing destination" Snowflake Connector

Affected: Data Export integration with Snowflake

Symptoms

This issue occurs when testing the LaunchDarkly Snowflake Connector during integration setup. The following error appears in the UI:

Error: Internal error testing destination

This error is displayed after running the required SQL setup statements. The LaunchDarkly UI does not provide specific feedback about which part of the configuration is causing the issue.

Cause

This error is typically caused by network policies or firewall restrictions. Most often, the issue occurs when your organization’s network does not allow inbound traffic from LaunchDarkly's static Data Export IP address: 35.192.85.117

If this IP address is not explicitly allowlisted, Snowflake blocks the connection attempt, resulting in a vague error.

Solution

Follow these steps to resolve the error:

1. Confirm that your organization’s firewall or Snowflake account network policy explicitly allows inbound traffic from 35.192.85.117.

2. Refer to the official LaunchDarkly documentation to review network allowlisting prerequisites for Snowflake integrations.

3. After updating your firewall or network policies, re-run the required SQL setup commands in Snowflake.

4. In LaunchDarkly, return to the integration setup screen and retry the connection test.

   • If the connection succeeds, the issue is resolved.

   • If the error persists, continue to the next step.

5. Generate a HAR file or collect network logs from your browser's developer tools and provide them when contacting LaunchDarkly Support for further assistance.
