Hi @Jon
I came from this post IMAP Email Node Does Not Trigger Workflow - #12 by Jon, with the same issue as I have mentioned there.
I did what you suggest by activating the “Force Reconnect” with 60s, but this didn’t solved the issue, the trigger goes stuck after a while (but the emails are marked as open…)
In fact, I have also tried by setting up another workflow that deactivate & activates the workflow containing the IMAP trigger, every few hours with a cron in order to “reset” it, but this did not solved the issue with the IMAP trigger neither.
Issue mentioning this workaround (doesn’t worked for me): IMAP Triggers randomly stop processing new messages · Issue #1400 · n8n-io/n8n · GitHub
