Problem with auhentication

Questions

Hey there!

I started to have an issue regarding authentication. The frontend displays the message “Workflow could not be activated: User is authenticated but not connected.” when I try to activate a flow. It happens even after a refresh.

I can see the following error in the logs:

I run the n8n on Google Cloud k8s, with no special configuration and only 1 replica.

Any clues?

Thanks!

Hi Victor, I am sorry to hear you’re having trouble. I was not able to reproduce this problem on my side by simply adding an IMAP trigger node to my workflow, so without additional details I can’t say for certain what’s happening here.

My first guess would be something preventing the connection to your specific IMAP server from working as it should. Perhaps a firewall or other security feature? Are you also having trouble when activating your workflow on a local n8n instance?

Hey @MutedJam

My flow actually only has a Webhook Node connected to a HTTP Request Node and then to Freshdesk.

The line which says “EmailReadImap” is not related. Sorry it was there.

This seems to be something with n8n authentication itself. I am using a very old version (0.175.0).

Thanks for checking it anyway.

Best,
Victor
