state or nonce does not matchstate

Cause probable. The state or nonce value returned is not the one the application kept: session lost in the meantime, blocked cookie, or several sign-in tabs open at the same time.

What to do? Keep state and nonce in a session that survives the redirect (suitable SameSite cookie). Avoid starting two sign-ins in parallel in the same browser.
