Payment Method Registration Errors [Error Code 401 and 601]

[AKS_Himiko]

So I have this same problem, it goes like this:
1- I log into the Mog Station (sometimes it just returns me to the log in window, even tho I know my credentials are correct and the 1-time password as well).
2- I go and try and subscribe with a Credit Card, and the 1 EUR minimum charge is made (I get a message from the bank with any transaction with my credit card).
3- When I get to the part where I confirm the payment, it gives me Error 406: Please try again later.

Now at any point in this process I actually may be redirected back to the log in page of the Mog Station or the SE Account management, why ? I don't know, I thought it was the browser, so I switched from Firefox to IE and Chrome, both with the same result, the one time I actually made it to the 406 Error was while I was on a VPN, hence I assume the problem is in my ISP or something, but no matter how I confirm the payment I always get the 406 error.
