Hello n8n Support Team / Community,
We are experiencing a critical issue with our official n8n Cloud instance following a recent version update.
The Problem
One specific user is receiving a persistent “Connection Lost” error in the top-right corner of the UI, which prevents them from using the service.
Crucial Context
This is not a server-wide issue. The second administrator/user accessing the exact same project on the same instance works perfectly fine without any errors. This isolates the problem to the specific user’s profile data.
Troubleshooting Performed (Failed)
We have confirmed and exhausted all client-side and session reset solutions on the affected user’s browser (Chrome):
Full Client-Side Cleanup: Performed an exhaustive wipe of all site data (cache, cookies, and local storage).
Session Token Reset: The affected user changed their password, logged out, and logged back in to force the database to invalidate and refresh the session token.
The error persists after both attempts.
Technical Diagnosis & Request
Since all client-side troubleshooting failed, this definitively suggests a corruption of the user’s session token, permissions, or profile data within the n8n Cloud backend database, which was triggered by the version update.
As this is the official managed n8n Cloud service, we kindly request the support team to intervene and manually reset or purge the affected user’s profile/session data in the database to allow a clean login.
Thank you for your assistance.
