The HSTS error in Google Chrome typically occurs when the website you are trying to visit has an invalid or expired SSL/TLS certificate. HSTS (HTTP Strict Transport Security) is a security feature that instructs the browser to always use HTTPS (encrypted) protocol for a specific domain, even if the user types "http://" instead of "https://".
When the SSL/TLS certificate of a website is invalid or expired, Chrome may not be able to establish a secure connection with the website, and therefore cannot load it. This results in a "Your connection is not private" error message, which can be caused by various factors such as incorrect system date and time settings, outdated Chrome browser version, or a misconfigured network proxy.
To fix the HSTS error in Chrome, you can try the following steps:
Check your system date and time settings: Make sure that your system's date and time settings are correct. An incorrect date or time can cause SSL/TLS certificate validation issues.
Update your browser: Make sure that you are using the latest version of Google Chrome. An outdated browser version may not support the latest SSL/TLS protocols.
Clear your browsing data: Clear your browser cache and cookies, as well as the SSL state. This can help fix issues related to SSL/TLS certificate validation.
Disable extensions: Try disabling any browser extensions that may be interfering with the SSL/TLS certificate validation process.
Contact the website owner: If none of the above steps work, you may need to contact the website owner and notify them of the issue. They may be able to fix the SSL/TLS certificate issue on their end.
