Describe the problem/error/question

Hi there, I am having issues with my n8n instance, where all my workflows cannot be saved and I am getting the error: Connection Lost where it used to show Save.
It was not an issue on the previous version and just started seeing this issue now.

What is the error message (if any)?

Conection Lost

Please share your workflow

All workflows in my n8n instance

Information on your n8n setup

  • n8n version: 1.88.0
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
  • Operating system: Google Cloud VM

Could you please explain in detail how to fix the problem? I’d really appreciate it, since I don’t have much experience with this, and my small business depends on a couple of projects I have running

I have the same issue with docker postgresql and nginx configuration starting from 1.88.0 version for all flows as well.

Try this solution

can confirm, this solved this on my instance as well. I’m using Nginx though, so add this to the confirm if it applies:

proxy_set_header Host $host;
proxy_set_header Origin https://n8n.example.com; # Replace with your actual domain
proxy_set_header X-Forwarded-Proto $scheme;

Where do I have to like these lines of code?

I get the same error, I assume it is a docker-compose.yaml update that is needed?

Where (what files) do these config setting need to be put?
