How to Resolve the Error Quickly
1. Clear Your Browser Cache and SSL State
Sometimes the error is local to your computer. Try clearing your browser cache or opening the site in Incognito mode. If the site loads, the issue was on your end.
2. Check Your Hosting SSL Configuration
Log into your hosting dashboard and ensure your SSL certificate is properly assigned to your domain without any misconfigurations in the server block (Nginx/Apache).
3. Scan for Server-Level Malware
Hackers frequently modify the .htaccess file or Nginx configurations to redirect traffic, which breaks the SSL protocol and triggers the "This site can’t provide a secure connection" error.
By installing Nexura Security, you can instantly scan your WordPress environment for configuration tampering. Nexura Security's Web Application Firewall (WAF) acts as a shield, preventing unauthorized modifications to your server files and ensuring your SSL handshake is never hijacked.
