Chrome your connection is not private solution

Your connection is not private

When I opened station b today, it was not a private connection that was intercepted. I tried many methods on the Internet, but it didn’t work. Finally, I refreshed the DNS to solve it. I would like to record it here. Attach the error screenshot first. Attackers may try to steal your information from

NET::ERR_CERT_INVALID
Help make Chrome more secure by sending the URLs of some of the pages you visit, limited system information, and some of the page content to Google. Privacy Policy
xxxx generally uses encryption technology to protect your information. When Google Chrome tried to connect to xxxx this time, the site sent back unusual and incorrect credentials. This could be because an attacker is trying to impersonate xxxx, or the Wi-Fi login screen interrupted the connection. Rest assured, your information is still safe, as Google Chrome terminated the connection without any data exchange.
You can't visit xxxx right now because this site sent messy credentials that Google Chrome couldn't handle. Network errors and attacks are usually temporary, so this page may return to normal at a later date.

Summary of online solutions

• Click the blank space with the mouse, type thisisunsafe on the keyboard and press Enter (I think this method can solve most of the problems. The disadvantage is that it needs to be entered every time, but it still doesn’t work for me)

• Right-click the desktop shortcut to enter the properties, select the "Shortcut" tab, add the following startup parameters at the end of the target : --test-type --ignore-certificate-errors, click the OK button Note: between chrome.exe and the parameters A space needs to be added between (I tried to tell me that it was invalid, so I didn’t study it any more)

• Reimport the ssl certificate (I couldn't find this certificate in my setup, tried unsuccessfully)
