Phone code always expired

[junjie870113]

I'm trying to do some test against this lib, although I can get the SMS code, the call to authSingIn always says that the SMS code expired.

the telegram client is deployed in Chicago(VPS node) while the phone is in China. I try to change the timezone to 'Asia/Shanghai' but still failed

can anyone help me?
