n8n Cloud instance inaccessible – Cannot GET on all routes

Describe the problem/error/question

Our n8n Cloud instance has become inaccessible. All routes are returning “Cannot GET”, including the root. The instance does not appear to be starting up at all. We have active production workflows dependent on this instance.

We’ve already opened a support ticket and it has been escalated to a human agent, but posting here in case anyone from the team can help move things along.

What is the error message (if any)?

Cannot GET /

Tip for sharing information

Pasting your n8n workflow


Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```

```

That implies to any JSON output you would like to share with us.

Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!


Your n8n Cloud instance should be accessible now.
If any issues still, please, reply to the ticket you raised with the Support team.
