Is it the network silver shield? I have seen it, too. First of all, the certificate will not be lost in the network shield, which is better than the dynamic password card. Then, the certificate selected at the time of payment is incorrect. Focus on solving the problem that under normal circumstances, the certificate will still be incorrect after the E-road escort runs. I've tried n times, too The last time was E-road escort inspection and maintenance. Don't close this software window and start paying, for example. If there is a certificate of choice, you can choose any one, as long as it is from CCB, you can pay successfully here. I'm a member of the BS Construction Bank, and I hope I can help you.
