Payment Method Registration Errors [Error Code 401 and 601]

[Bluevann]

This just happened to me as well. Thankfully my XIV payment went through a couple days ago, but today my XI subscription was supposed to bill and instead I got deactivated. My last CC's operation was paying for the Fan Fest premium Live streaming. Wonder if that is somehow connected.

EDIT: It turns out I was right. The errors 401 and 601 on the account management were caused by the fact that the CC was already in the process of being locked by my bank for suspected fraud, and the transaction that raised this suspicion was the TwitchTV subscription to the Premium streaming for the FanFest.
