Use the same working editor URL you already have today. This is the route that keeps n8n secured and usable right now.
This button opens the local n8n endpoint that becomes available after you start the SSH tunnel. It is a different path from the public HTTPS URL and is the real fallback way in.
Open a tunnel through the VPS recovery SSH door, then browse locally to n8n. This is meant to stay usable even if the public IP or DNS path changes later.
ssh -L 5678:127.0.0.1:5678 <SSH_USER>@2.25.203.214
# then open:
http://localhost:5678
<SSH_USER> with the same SSH account you already use for admin/recovery access on the VPS.
