Troubleshooting

Integration and sync problems

A connection says its credential is no longer accepted, events stopped arriving, Google Calendar is out of step, or files did not transfer.

Updated 2 November 2026

When a connection to another service stops working, the cause is usually an expired sign-in, a background update that lapsed, or something that is not supported yet.

Google Calendar is out of step#

See Import from Google Calendar.

A mailbox stopped receiving or sending#

Reconnect it in Email → Accounts: sign in to Gmail or Outlook again, or re-enter your SMTP and IMAP details. A mailbox connected with SMTP but no IMAP can send but cannot see new mail or replies. See Email and Email problems.

An automation step that uses Google fails#

Append to Google Sheets, Create event in Google Calendar and Save attachment to Google Drive use your Google connection. If it has expired, reconnect Google and run the automation again. See Runs, errors and retries.

Webhooks are not arriving#

  • Into an automation — check the address uses the right automation and token. A 401 means the token is wrong; a 403 means it belongs to a different automation. See Webhooks in and out.
  • Out of Unobits — outgoing webhook deliveries are not retried. If your endpoint was down, the event is not sent again.

Booking channels show the wrong nights#

Channel calendars (Airbnb, Booking.com) are read again when Bookings is opened, at most every half hour; there is no background refresh yet. Open Bookings to pick up changes. See Resources → Channels.
