WhatsApp server returns abnormal data，why?

[RamboNie]

Some WhatsApp accounts are successfully logged in. After about 1 minute, the WhatsApp server will return byte[] [-8, 1, 2], and then the parsing exception will occur and the connection will be disconnected. Can anyone help confirm this? Thanks very much
