Error message

Connection token exchange failed

What it means

Token-exchange failure in the child/derived token flow: the broker's HTTP response was non-2xx. The error carries the upstream code (mapped to credential_revoked when the parent was revoked), status, and request id; the upstream broker rejecting the exchange is at fault.
