Hi! Other users have reported similar error codes when using the SW App or Mobile Website. Sometimes this could happen if there's an IT-related network or device conflict. I would first try rebooking the flight but through the full/desktop version of the SW website and/or via a different network connection (e.g.: different Wi-Fi network and not through a VPN). 

Note that sometimes, the error could also be related to the SW Rapid Rewards account; if that's the case and the transaction still fails across the board via the self-service booking options, I would certainly give SW Customer Service a call:

Call the displayed phone number and they should be able to help you with your booking.

Hope this helps!
