When your chorme or edge browser encounters this problem when you open a webpage, don’t change hosts, modify DNS address, or modify WLAN attributes... Your connection is not a dedicated connection. How to solve it:
1. Open the Control Panel under the computer start option.
2. Then click System and Security.
3. Click on the Windows Defender Firewall option.
4. Click to enable or disable the WindowsDeferder Firewall option.
5. Finally, check the windows deferder firewall function to solve the problem that your link is not a dedicated link.
Sometimes it appears that your connection is not a dedicated connection, you just need to:
1. Adjust the keyboard to English input state;
2. Refresh the page and click anywhere on the current page with the mouse;
3. Press the keys one by one: thisisunsafe (note here: it is un, don’t type s to become sun);
4. After pressing the above buttons, the page will automatically refresh, and then you can visit normally (if there is no response, you can click Enter).
