Does anyone know why a standard Data Action configured to push call disposition data to a NICE CXone endpoint is consistently failing with a 504 Gateway Timeout in the EU-West BYOC environment? The integration was stable for three months, but since the last platform update, the timeout rate has increased to approximately 40% of all transactions. The Performance Dashboard indicates that the Architect flow is processing the data correctly, as the subsequent IVR prompts are triggered without delay. However, the external system does not receive the payload, and the flow logs record a generic connection failure rather than a specific application error.
The configuration uses the standard HTTPS POST method with basic authentication. The payload size is minimal, under 2KB, which should not trigger any bandwidth limitations on the BYOC edge. The endpoint has been verified as responsive using external testing tools, returning 200 OK within 200ms. Despite this, the Genesys Cloud Data Action times out after the default 10-second window. Increasing the timeout duration in the Data Action settings to 30 seconds has not resolved the issue, suggesting the problem lies in the initial handshake or routing rather than processing time.
Action Type: Data Action
Endpoint: https://api.nicecxone.com/v1/dispositions
Method: POST
Auth: Basic
Headers:
Content-Type: application/json
X-Request-ID: {{interaction.id}}
Timeout: 10s
Retry Policy: 3 attempts, 5s interval
The business impact is significant, as the lack of disposition data in NICE CXone prevents accurate agent performance reporting and queue analytics. The Performance Dashboard shows no anomalies in agent adherence or queue wait times, isolating the issue to the data synchronization layer. Is there a known latency issue with the EU-West BYOC edge when communicating with external NICE endpoints? Should the connection be routed through a specific proxy or gateway to ensure stability? The current setup relies on direct outbound traffic from the Genesys Cloud infrastructure. Any insights into recent changes affecting Data Action reliability in this region would be appreciated. The goal is to restore the data flow without redesigning the entire integration architecture.
