New n8n docker instance often shows Connection Lost

I am getting a few different errors, and I really haven’t started building anything on the docker instance.

I am able to login, but as soon as I add one node, and try to save it, I see.

Problem with importing workflow.

and if I go to the root /workflow page I sometimes see this error.

When I try to import a workflow that I created using the Desktop version I see this error

Information on your n8n setup

  • n8n version: 0.190.0
  • Database you’re using (default: SQLite): Default
  • Running n8n with the execution process [own(default), main]: Default
  • Running n8n via [Docker, npm,, desktop app]: Docker

Sorry to hear that you have problems! Did you follow the Server Setup guide in our docs or do you run it differently? Very often do we see problems if, for example, a reverse proxy in front of n8n is used that is not configured correctly to work with n8n and Server-Sent Events.
The 401 status code means “unauthorized”, could theoretically also be caused by a reverse proxy.
