Shanghai Railway Information Network has never been able to log in.

Too many logins, browser problems, unstable network speed, etc.

1. Too many logons: A large number of users visit the website at the same time during the peak period, which will lead to the overload of the server and prevent some users from logging in successfully. Try to log in during off-peak hours.

2. Browser problems: Sometimes browser cache or plug-in problems will affect the normal loading and login of the website. You can try to clear the browser cache, disable plug-ins or reinstall the browser to solve the problem. You can also try using a different browser to see if you can log in successfully.

3. Unstable network speed: There is a problem with the network connection or the network speed is slow, which will lead to the failure to open the webpage smoothly and complete the login operation. It is suggested to check your own network connection and test and optimize it through some tools such as Tencent Computer Manager to improve the stability of the network.
