Netease can't receive Twitter verification code

What you want to ask is why Netease can't receive Twitter verification code? Mailbox server problems, network problems, etc.

Email server problem: Netease's email server will fail, resulting in the inability to receive Twitter verification code. Please try using a different mailbox server or try again later.

Network problem: Due to network failure or network delay, Twitter verification code cannot be received in time. Please check whether the network connection is normal and try to resend the verification code.
