Hey @Sourabh_Pawar1,
Welcome!
that “Connection lost” banner is usually not about your internet speed. Most of the time it’s the browser losing its live connection to n8n (WebSockets/SSE), especially if you’re self-hosting behind a proxxy.
If you’re behind Nginx / Nginx Proxy Manager / Apache / an Ingress, first make sure WebSockets are enabled on the proxy. Without that, n8n can be running fine but the UI will constantly show “Connection lost”. For Nginx, your location block needs the usual Upgrade / Connection headers and a longer read timeout. In Nginx Proxy Manager, just enable the “Websockets” toggle for that host.
If this started right after an n8n upgrade, it can also be version/proxy related. In a few reports, people fixed it by either updating to the latest stable or rolling back one minor version if the timing matches.
Quick sanity checks: try another browser, and open DevTools → Network and look at the websocket/push request, if it’s reconnecting or failing, it’s almost always proxy/WebSocket config, not bandwidth. If you can’t get WebSockets working in your setup, a simple workaround is switching to SSE: N8N_PUSH_BACKEND=sse
If you share your n8n version + Cloud vs self-hosted + what proxy you’re using, I can tell you the exact place to change.
