Permanent "Connection lost" error for n8n next

Describe the problem/error/question

I cant perform any action and save any change for n8n since updating to beta version due to “Connection Lost” error. All workflows built before update work as expected, though

What is the error message (if any)?

No errors in n8n container log

Information on your n8n setup

  • n8n version: 1.0.3
  • Database (default: SQLite): SQLite
  • n8n EXECUTIONS_PROCESS setting (default: own, main): default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): docker-compose
  • Operating system: Linux

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
