Error code 31202

[Pokemaniac1993]

Whilst searching for the Mewtwo event pokemon I receive this code, as reported earlier the nintendo website does not contain this error code.
I can connect to dream world and all the other online features perfectley well, I test every day and this is my 3rd day receiving the error.
Any help? ;484;

It came up with a result for error code 31202 on Nintendo's site, but for the 3DS.

Are you using a 3DS?
