n8n - 💡(How to fix) Fix You have a connection issue or the server is down. n8n should reconnect automatically once the issue is resolved - n8n cloud

Here’s a cleaned-up version you can paste into the n8n support/community template:

Describe the problem/error/question

I am facing a persistent connection issue in n8n Cloud whenever I open one of my workflows.

The workflow editor keeps rapidly toggling between an active/connected state and a connection error state. This happens continuously, almost every few milliseconds, so I am unable to run or test any workflows at all.

The issue appears immediately when I open the workflow canvas. I have tried waiting to see if it reconnects automatically, but the problem keeps repeating and does not stabilise.

What is the error message (if any)?

The message shown is:

You have a connection issue or the server is down. n8n should reconnect automatically once the issue is resolved.

Please share your workflow/screenshots/recording

The workflow itself is not running because the editor keeps switching into the connection issue state before I can execute anything.

I have not pasted the workflow here yet because the issue seems to happen at the editor/connection level rather than with a specific node execution.

Share the output returned by the last node

No node output is available because I cannot run the workflow. The connection issue prevents me from manually executing or testing the workflow.
