Hi @WDN2010, starting with version 1, n8n would use websockets instead of Server-Sent Events:

I reckon your current setup (possibly a reverse proxy or perhaps a load balancer) might block the websocket connection between n8n and your browser. So perhaps you can try setting N8N_PUSH_BACKEND=sse and see if this works for you?

Thanks! It was enough for me to enable websockets support in Nginx Proxy Manager settings and problem was gone
