Why Does 'Connection Lost' Appear Instead of the Save Button in n8n on My AWS EC2 Server?

I have installed n8n on an AWS EC2 server. Although I can log into my n8n account and use its features, the upper right corner—where the “Save” button should be—displays “Connection lost.” I’ve checked the AWS server, and everything appears to be running normally. Unfortunately, I’m unable to pinpoint the cause of the issue. Could you please provide me with some troubleshooting tips?

Information on your n8n setup

  • **n8n version: Version 1.83.2
  • **Running n8n via Docker

hello @myvisuell

Do you have an ALB in front of the n8n instance?

Connection Lost usually means your session is expired and you need to re-authenticate (refresh the browser page, or open another one and see if there is a login screen appears) or if there are some issues with the websockets/proxy/alb
