I really wish someone would read these posts because I am having the same issue. Can I just say that I AM FURIOUS with this situation just like you all. I have been a subscriber for 6 months off and on and I have never had any problems until yesterday. For now I got a 60 day digital gamecard, but I am very unhappy with that because I feel that I have been scammed into buying that since it's more expensive. Unfortunately it was literally the only option available for me to be able to start my subscription yesterday to get some last minute raiding and tomes in before the reset. Furthermore I don't like the extended amount of time as I don't want to become totally enslaved to this game so in between months I take a week or two off in order to get some real life things done.
Anyways this time when I tried to buy crysta doing the exact same thing I've been doing for 6 months, I got an error 401, both with my credit card AND with my debit card. I also got error 601 when I tried to extend my subscription directly using Mog Station. I have never had this problem before and I did not do anything different whatsoever than I did the previous 6 times. So I put in a ticket and this was the response:

Dear Customer,
Regarding your request for billing support. Please find your answer below.
If you are receiving an error 601, 406, or error 401 when attempting to update your payment method, then there is an issue where the financial institution is declining the authorization attempt. Unfortunately as SQUARE ENIX is not the financial institution, we are not provided with any information as to why the authorization was declined, only that it was. Please confirm that all billing information is entered correctly on the SQUARE ENIX Account in question. Please also note that once an authorization has been rejected, that form of payment cannot be attempted again for a full twenty-four hours, and any further attempts before that time will automatically be rejected. If you would like further information about this specific authorization attempt, please contact your financial institution.
(I did contact my financial institution and it has nothing to do with it. The financial institution is not declining my authorization attempt, the website has a bug in it.)
Please ensure the personal information listed on the Square Enix account matches the information listed on the credit / debit card. For example, name of the Square Enix account holder must match the name that's listed on the credit / debit card itself. Keep in mind that only certain pieces of personal information on a Square Enix account can be adjusted (street address and email address) after creation.
(I will need to change the name on my account because it isn't my name it's just a bunch of random keystrokes because when I set up the account I was hesitant to trust the website.)
Make sure that the card you're trying to use isn't already being used to pay for another account. Problems may arise if the an attempt is made to use the same card to bill two separate accounts simultaneously. If this is indeed your situation, please wait 24 hours between reactivation attempts
(It isn't. Even so, nobody should have to wait 24 hours to give you money. Please fix this.)
Make sure that your card provider allows $1.00 preauthorization holds. This billing attempt is made in order to make sure that the account is valid for billing. After 1 to 2 business days, these funds will be placed back on the account. If your card issuer does not allow such preauthorization holds, you may want to contact them.
(It does.)
If you attempted this method of payment multiple times with a failed result, there is a possibility of a longer block being placed on the account. This block can last 30 days.
Thank you for contacting the SQUARE ENIX Support Center.
(This is unbelievably ridiculous. For someone trying again because they thought they may have made a mistake with the credit card number this is very unforgiving.)

I spent like 3 hours of my life that I will never get back trying various things until I finally was able to get a 60 day game time card. I am also extremely angry that I was scammed into this option due to the other methods not working. I can't believe a company that has however many millions of customers world wide could possibly screw this up this bad FOR OVER A YEAR WITH OVER A THOUSAND POSTS ABOUT IT ON THIS THREAD. Normally I pay $12.99 for 30 days but this time I paid $31.79 for 60 days. I don't know how we can get our voices heard but to be honest I would expect that any customer service worth anything would take 30 days off of my subscription and refund me $18.80 at the very least. A step above that would be to send me an apology for the bad system and the time I wasted on its account. Furthermore this should be addressed publicly and dealt with and we should be given a date that this issue will be fixed by.
It just boggles my mind WE ARE TRYING TO GIVE YOU MONEY FOR HEAVEN'S SAKE!
