This situation is a common problem after CFCA upgraded Minsheng Online Banking at the end of last year. First of all, adjust the security level of the computer you are using to intermediate level, and try to close the 360 firewall. If it still doesn't work, call Minsheng customer service at 95568-0-5, and transfer to the online banking dedicated line for manual service, so that the staff can lead you to do some operations. Don't worry, this problem is easy to solve under normal circumstances.
