The server IP address cannot be found and the webpage cannot be opened.

When trying to open the webpage, I encounter If you cannot connect to the server, it may be because the server IP address cannot be found. Here are the steps to resolve this issue:

1. Refresh the page

First, try refreshing the page. Press the F5 key or click the refresh button on the browser toolbar. This may reload the page and may resolve the IP address issue.

2. Check the network connection

Make sure the computer is connected to the Internet. Check if the Wi-Fi or Ethernet connection is working properly. Try disconnecting and reconnecting to refresh the IP address.

3. Restart the browser

Close the browser and reopen it. This will clear your browser's cache, including incorrect settings that may be causing IP address issues.

4. Clear the DNS cache

The DNS cache is a local database that stores known correspondences between domain names and IP addresses. Occasionally, the IP addresses stored in this cache may be out of date or incorrect. Clearing the DNS cache can resolve this issue.

For Windows users:

• Press Win R to open the Run window.
• Enter "ipconfig /flushdns" and press Enter.

For macOS users:

• Open Terminal.
• Enter "sudo dscacheutil -flushcache" and press Enter.

5. Use a public DNS server

If clearing the DNS cache doesn't work, you can try using a public DNS server such as Google Public DNS or OpenDNS.

For Windows users:

• Open Control Panel > Network and Internet > Network and Sharing Center.
• Select the current network connection and click "Properties".
• In the Network tab, select Internet Protocol Version 4 (TCP/IPv4).
• Click "Properties" and select "Use the following DNS server addresses."

• Enter the following IP address:

  • Preferred DNS server: 8.8.8.8
  • Alternate DNS server: 8.8.4.4

For macOS users:

• Open System Preferences > Network.
• Select the current network connection and click "Advanced".

• In the "DNS" tab, click the " " button and enter the following IP address:

  • 8.8.8.8
  • 8.8.4.4

6. Contact the site administrator

If the above steps don't work, the problem may be with the site itself. Try contacting the website administrator to see if there is a problem with the server.
