Problem Analysis P:
After the user enters the user name and password, the web authentication server authenticates the user and sends the authentication packet to the NE40E. As a result, the user fails to go online. After further comparison, it is found that the MD5 encryption algorithm of the web authentication server is different from the NE40E MD5 encryption algorithm. As a result, the NE40E fails to pass the check.
Log information that the authentication check message failed:

Comparison between the web authentication server and NE40E MD5 encryption result:
Solution:
Check whether the shared key of the web authentication server and NE40E are the same.
If the shared key is the same, please adjust the MD5 encryption algorithm of the web authentication server to the standard encryption algorithm.
