I've bought fantasia potions from the mog station as recently as 5 or 6 days ago using my visa debit card, that same card was used for my last subscription to the game and the info was saved for recurring billing (meaning all my card details are correct, no user error there). I have over 80 dollars in the account too. Adblock is disabled, as well as any other browser extensions, I have tried on Chrome and Firefox. I tried using the card to purchase cheap dlc for a game on steam and it worked. Yet when I go to purchase anything on the mog station now or try to update my card info (my subscription auto renew didn't work either so now I'm unable to play the game) it gives me error 401 and error 601. (401 when trying to buy fantasia potions and 601 when trying to update card details for subscription.) I had this problem yesterday, waited 24 hours and it's still here today. I don't understand what the problem could be, all things indicate its a problem on square enix's end but I've seen no evidence online that anyone else is experiencing the same issue as recently as me.
