The data signature of Bank of Communications 100 18 failed.
Hello, I would like to ask the reason why the data signing of Bank of Communications 100 18 failed? Bank of Communications failed to sign the data. 100 18 is a system problem. Because the ip field 100 18 appears in the prompt, that is, the long and short networks sometimes replace the ip field in the communication content, resulting in the data being tampered with and the verification signature being reported incorrectly, so there is a system problem.
