Error Code 204001 after a ListETickets Request Type

[Ocarinaoftime]

When using custom servers for each of the main .shop.wii.com subdomains (ecs, ias, and oss-auth), after the server sends a response for the ListETickets request type, the client outputs a 204001 error. According to one of the JavaScript files in /oss/oss/common/js/, the suffix 001 means that it is a generic error. (I think this is correct but I might be wrong). The server never puts an error code in the XML response so I am very confused. This does not happen on the original servers as I am able to connect and go shopping for the little that is left.
