My connection broke or says reconnect — what do I do?

Tokens expire on the provider's schedule, and some providers drop a connection when a password changes or an admin revokes an app. Reconnecting is a full re-authorisation and it picks up where the sync left off rather than starting the 365-day pull over. When Stripe is the one that broke, customers can't pay your invoices by card or bank until you reconnect: the line at the top of DeskOps says "Stripe needs reconnecting; you can still send invoices for check or cash", and an open invoice's pay page asks the customer to contact you to pay.
