What is the error message (if any)?

‘‘your account is temporarily blocked for imap use”. i contacted my email provider (zoho mail) and they informed that there are >100 unclosed and active connections from server end. i checked all my workflows and executions and there are no running or queued executions. let me know the reasons i’m facing this issue. i’m pasting only the imap node below as the issue is related to it. note that the workflow was in production until 5th jan and the first unclosed active connection is on 6th jan 10am

Looks like the IMAP connections aren’t being properly closed after execution. Try enabling the “Force Reconnect” option in your IMAP node settings - this ensures connections are closed after each execution. Also, check if you have any workflows with IMAP nodes that might be running in the background or stuck in a loop. Let me know if enabling “Force Reconnect” resolves the issue!

Looks like the IMAP node isn’t properly closing connections after execution. Try adding the `forceReconnect` option (set to 1) in the IMAP node’s Advanced Options - this forces a fresh connection each time. Also, check if your workflow has any unhandled errors that might prevent proper connection closure. Let me know if this helps!
