Fujian school health information verification system cannot log in.

Fujian school health information verification system can't log in due to network problems. The existence of loops in the network will slow down the network speed. In some complex networks, there are often redundant spare lines. If you connect carelessly, a loop will be formed, and data packets will continue to send and check data, thus affecting the overall network speed. Unstable network speed will make it impossible to log in.
