Can not get get_account_transactions

Yesterday, I can test ok. But today get it return:
“code”: -32600,
“message”: “Invalid Request: could not find account by address F68432F510623EAEE84ED3A6FA2A9342”

Was it after the reset? create a new address and try it again , this happened to me when trying to get an old address that has Coin1 instead of XUS
