Mobile Website Checkin Error

It seems as though since the implementation of the new SW reservation system, for numerous checkins this month I have been receiving the error "Boarding pass can be obtained at airport, Mobile boarding pass in not available. Error: 403599307" when trying to checkin for my flight on the mobile website right at the 24 hour mark. After a couple of retry's it finally goes through. Any ideas on whats causing this issue? I havent been able to check in on the desktop site or use the mobile app yet for my t-24 checkin and wonder if those are also experiencing this issue?
