Online League Error

My online league, which is in its 2nd season, started getting this message in the attached photo: "The requested league is temporarily unavailable. Please try again later. We apologize for any inconvenience. You have been returned to the Franchise Launcher.", last night when one of my league members tried to open the franchise. Everyone in the league is unable to access the league. Is there any way to fix this? We have put a lot of time into this league, and would be disappointed if we are unable to save the league.
