What if the computer can't open the webpage?

Network connection problem: Please make sure that your computer is connected to an available network and the network connection is normal. Try to visit other webpages or use other devices to confirm whether only one computer can't open webpages. Clear browser cache: Browser caching files may cause web page loading problems. You can try clearing your browser's cache file and then visit the webpage again. Check firewall settings: Firewall settings may block access to specific websites. Check your firewall settings to ensure that the required websites are not blocked. Check the proxy settings: If a proxy server is configured on your computer, make sure that the proxy settings are correct. Try deactivating the proxy server or changing proxy settings, and then try reopening the webpage. DNS problem: try to refresh the DNS cache to solve the domain name resolution problem. Enter the command "ipconfig /flushdns" at the command prompt, then restart the computer and try to open the webpage again. Router restart: If other devices can access the Internet normally, only this computer can't open the webpage, so you can consider restarting the router to solve the network connection problem. Virus or malware: Sometimes, malware can interfere with network connections. Conduct a comprehensive anti-virus scan to ensure that the computer is not infected by viruses or malware. Check the network settings: Enter the network settings of the computer and make sure that the IP address, subnet mask, default gateway and DNS server are set correctly.
