How long does the PSN WC-40378-2 lockout last?
Error WC-40378-2 is a rate limit lockout triggered by too many failed attempts in a short period. PlayStation does not state an exact duration, but community reports indicate the lockout typically lasts between 1 and 24 hours. Do not make any further attempts during this time — every attempt can extend the lockout. Wait the full 24 hours, sign out and back into PSN, then try redeeming at store.playstation.com. If still locked after 24 hours, contact PlayStation Support.
