Hi guys!,
I recently upgraded my production n8n vversion from 1.50.x to 2.15.x (actually to 2.16.2 but then donwgraded it). and I am getting this offline message at the top right corner instead of publish option.
FYI: I have hosted this n8n on gcp cloud run, also I have added this flag in my YAML: N8N_PUSH_BACKEND=sse
good day @User1_Development
I’d check is browser/session state after the upgrade. Sometimes after major version changes, cached frontend assets or stale cookies can cause the editor to think it’s offline even when the backend is healthy. I’d try a hard refresh, private/incognito window, or clearing site data first. I’d also check whether the issue happens for all users/browsers or only one session. If it affects everyone, then it’s more likely infrastructure-related; if it’s only one browser, it may be client-side state rather than Cloud Run itself.
hi @User1_Development Welcome! Cloud Run kills SSE connections at the default 300s request timeout, that’s why your editor flips to “No network connection” — bump the timeout to max on your service with gcloud run services update YOUR_SERVICE --timeout=3600 and make sure you have --session-affinity enabled if running multiple instances. are you on a single Cloud Run instance or autoscaling?
Hey! @achamm , Thanks for responding, I think you might be right, let me try this as well.
And to answer your question it is on autoscaling.
Thank you very much for replying. Good Day to you as well @tamy.santos !!,
I tried clearing the cookies and opening the service in incognito mode and also tried opening it a separate browser but no luck!.
