Claude output

"I found the root cause in the browser console. The "Connection lost" issue is being caused by a repeating WebSocket failure paired with rate-limiting on n8n's telemetry endpoint:

The WebSocket client keeps logging [WebSocketClient] Connection lost, code=1005 and "Attempting to reconnect in 1000ms" every few seconds in a tight loop.

At the same time, requests to /rest/telemetry/proxy/v1/identify are returning HTTP 429 (Too Many Requests) repeatedly.

WebSocket close code 1005 means the server closed the connection without sending a status code, and combined with the 429s on the telemetry endpoint, this points to n8n's push/telemetry service rate-limiting your session — not a problem with your local Chrome, network, or extensions. That's why disabling extensions and hard-refreshing didn't help: the issue is server-side throttling on the n8n Cloud side, and your client is stuck in a reconnect loop that keeps re-triggering it."
