RE: Websocket disconnects by remote and cannot reauthenticate account

tisha56morris said: 

Hello,
Let me break this down and provide some insights:

WebSocket Closure with Code 1000: This code indicates a normal closure, meaning the connection was closed intentionally, either by the server or client, after fulfilling its purpose. However, if this happens unexpectedly, it could be due to:

Server-side timeouts or resource constraints.

Network interruptions or unstable connections.

Missing or delayed "ping/pong" messages to keep the connection alive.

Reconnection Issues: The error "No environment connection" suggests that the WebSocket server might not have fully re-established its state or environment after the reconnection. This could happen if:

The server requires additional time to reset or reinitialize resources.

The authentication process is being attempted too quickly after reconnection.

Suggestions to Address the Issue:

Implement Exponential Backoff: Instead of reconnecting every 3 seconds, try increasing the wait time between reconnection attempts (e.g., 3s, 6s, 12s). This gives the server more time to stabilize.

Check Server Logs: Look for any errors or warnings on the server side that might explain the disconnections or failed authentications.

Keep-Alive Mechanism: Ensure your application sends periodic "ping" messages to keep the WebSocket connection alive.

Error Handling: Add logic to handle specific errors like "No environment connection" by retrying the authentication process a few times before closing the WebSocket.

Testing and Debugging:

Test the reconnection logic in a controlled environment to simulate server restarts or network interruptions.

Use tools like WebSocket debuggers or network analyzers to monitor the connection lifecycle and identify potential bottlenecks.

Hello tisha56morris,

thanks for the feedback.

The disconnection with code 1000 had remote flag set to true, so is been closed intentionally by the websocket server.

I ping the websocket every 20 seconds.

In all the tests I've done (turning off and on the network connection and not pinging the ws) the reconnection was working properly at first attempt.

I'm gonna implement an exponential backoff system as you suggested hoping it's gonna solve this issue.

Thanks again for your assistance.
