This exact message is shown whenever Sprwt could not get a working Stripe login link for the account on your kitchen location - the page falls back to it any time creating the link fails or throws an error, without saying which specific reason applied. Possible causes include invalid or outdated stored keys, a closed account, or a temporary Stripe API error; the code does not distinguish between them for you. Re-run onboarding from Stripe > Connect if the location shows as not connected there; otherwise contact support so they can check the account and keys.
