Hi there! I see you're having trouble logging into the PlayStation App or website, and you're getting a "connection is not private" error. Let's work through this together.

To start, could you please tell me if this occurs both on the PlayStation App and when accessing the website through your browser on Windows 10? Also, have you noticed if this happens on multiple browsers or just one?

In the meantime, here are some initial steps to try that often help with private connection errors and login issues:

1. Clear your browser cache and cookies: Sometimes corrupted data there can cause security errors. On your browser, go to settings, find privacy or history, and clear cached data and cookies.

2. Try using a private/incognito window to access the site: This disables extensions and uses a fresh session, which can avoid some issues.

3. Check your system date and time settings: An incorrect date/time can trigger certificate errors leading to "connection not private" messages.

4. Restart your router and PC: This refreshes your network connection, which can resolve temporary glitches.

5. Disable any VPN or Proxy: These might interfere with secure connections to PlayStation's servers.

6. If on a browser, update it to the latest version or try a different browser.

If after trying these you still get the error, it may be related to security certificates or PlayStation servers. In that case, I can guide you through checking advanced browser settings or account recovery steps.

Let me know which steps you've tried already or if you need help with any of these!
