1. Network connection problem: Please make sure your network connection is normal. You can try to restart the network device or change the network connection mode to check whether other websites or applications can access normally.
2. Website maintenance or failure: It may be because of system maintenance or failure that it cannot be accessed. You can try visiting again later, or contact the relevant technical support department for consultation.
3. Wrong user name or password: Please make sure that the user name and password you entered are correct, and pay attention to case sensitivity. If you forget your password, you can try to reset it through the password recovery function.
4. Browser compatibility: Different websites may have different requirements for browsers. It is recommended to try to change different browsers, such as Chrome and Firefox, and make sure that your browser has been updated to the latest version.
5.IP address restrictions: Some websites may restrict specific IP addresses. If your IP address is blocked or restricted, you may not be able to access the website.
If you still can't solve the problem after trying the above solutions, I suggest you contact the technical support team of Shandong Education System Health Management Platform for further help and consultation.
