Agent Script Node Failing with 502 Bad Gateway in Architect Flow

My current config is completely failing…

We have implemented a new compliance script within an Architect flow for the Paris region. The script is hosted on an internal server and accessed via the Agent Script node. When agents attempt to play the script during a conversation, the system returns a 502 Bad Gateway error immediately. This occurs consistently across three different agents and two separate queues.

The script file is a standard MP3 format, approximately 2MB in size. The URL is accessible via browser from the office network, confirming no firewall blocks exist for standard HTTP requests. However, the Genesys Cloud platform seems unable to retrieve the resource when invoked through the flow.

Is there a specific requirement for the hosting environment regarding CORS headers or SSL certificates that might be causing this 502 error? We are using the latest version of the Architect tool. The error log in the conversation detail view simply states “Script playback failed: 502 Bad Gateway” without further context. We need to resolve this before the next shift starts at 17:00 CET.

The system returns a 502 Bad Gateway error immediately.

Have you tried increasing the timeout in the Agent Script node configuration? The default limit is often too low for external MP3 retrieval, so setting it to 30000 ms usually resolves the gateway timeout during load tests.

Take a look at at the CORS headers on your internal server, as the Genesys Cloud player often fails with a 502 if the origin isn’t explicitly allowed.

The timeout suggestion above misses the point because the connection is likely being rejected before any data transfer occurs. Ensure your server returns Access-Control-Allow-Origin: * or the specific Genesys Cloud domain.
