troubleshooting significant stability issues within our Genesys Cloud AppFoundry integration. The application acts as a bridge to NICE CXone Cognigy bots for complex IVR flows. The primary symptom is that the WebSocket connection to the AppFoundry endpoint drops after approximately 45 to 60 seconds of active audio streaming. This results in a hard disconnect for the caller and noticeable audio latency prior to the drop.
The AppFoundry application is deployed on a standard AWS EC2 instance with a public load balancer. The connection is established via the standard Genesys Cloud WebSocket protocol. We have verified that the server-side handshake completes successfully with a 101 Switching Protocols response. The initial JSON payload sent to the client contains the correct session ID and audio configuration.
The issue appears to be related to the keep-alive mechanism or the handling of binary audio frames. When we monitor the network traffic, we observe a steady stream of binary frames. However, after the 45-second mark, the server sends a close frame with code 1001 (Going Away). The client (Genesys Cloud platform) does not attempt to reconnect automatically in this specific context, leading to the call drop.
We have attempted to adjust the pingInterval and pingTimeout settings in our Node.js WebSocket server implementation. The current configuration is as follows:
const WebSocket = require('ws');
const wss = new WebSocket.Server({
port: process.env.PORT || 3000,
pingInterval: 30000,
pingTimeout: 10000
});
Despite these adjustments, the connection still terminates. We suspect that the Genesys Cloud platform has a stricter timeout for idle binary frames or that our server is not responding to the platform’s ping frames correctly. We have also checked the AppFoundry application settings in the Genesys Cloud admin portal. The timeout settings are set to the default values. We have not seen any specific documentation regarding the expected latency or keep-alive requirements for audio streaming via AppFoundry.
We are looking for guidance on the correct WebSocket configuration to maintain a stable audio stream. Specifically, we need to know if there are any specific headers or payload structures required to keep the connection alive. We have also considered implementing a custom heartbeat mechanism within the binary payload, but we are unsure if this is supported by the Genesys Cloud audio streaming protocol. We have reviewed the AppFoundry developer guide, but it does not provide detailed information on WebSocket keep-alive strategies for long-running audio sessions. We have also checked the network logs on our load balancer. There are no signs of connection resets or timeouts at the infrastructure level. The issue seems to be isolated to the application layer and the interaction with the Genesys Cloud platform. We have also tested the connection from different geographic locations. The behavior is consistent across all regions. We have not observed any correlation with network latency or packet loss. We are currently using the latest version of the Node.js WebSocket library. We have also tried using the raw ws module without any additional middleware. The issue persists. We have also checked the Genesys Cloud event logs. There are no specific errors or warnings related to the AppFoundry connection. We have also reached out to Genesys Cloud support. They have suggested that the issue might be related to the server’s handling of the WebSocket frames. They have not provided any specific code examples or configuration guidelines. We are looking for community input on this issue. We have also considered migrating to a different hosting environment. We have not seen any reports of similar issues with other hosting providers. We have also checked the Cognigy integration settings. The bot is configured to handle long-running conversations. We have not seen any issues with the bot’s response times. We have also checked the audio quality. The audio is clear and without distortion prior to the drop. We have also considered implementing a retry mechanism on the client side. We are unsure if this is supported by the Genesys Cloud platform. We have also checked the AppFoundry application’s resource usage. The CPU and memory usage are within normal limits. We have not seen any signs of resource exhaustion. We have also checked the network bandwidth. The bandwidth is sufficient for the audio stream. We have not seen any signs of bandwidth saturation. We are looking for any insights or workarounds that might help us stabilize the connection. We have also considered using a different protocol for the audio stream. We are unsure if this is feasible within the AppFoundry framework. We have also checked the Genesys Cloud API documentation. We have not found any specific guidance on WebSocket keep-alive for audio streaming. We have also checked the community forums. We have not found any similar issues reported by other users. We are looking for any feedback or suggestions. We have also considered reaching out to NICE CXone support. We are unsure if this is a Genesys Cloud or CXone issue.
