Identifying the Problem

Common Causes of the Issue

  1. SSL Certificate Issues:
    • Your website may have an expired, invalid, or improperly configured SSL certificate.

Step-by-Step Guide to Resolving the Issue

  • Update Software: Ensure that your server software and any related dependencies are updated to the latest versions.

3. Adjust Network Settings

  • Check Router Configuration: Sometimes, router settings may need tweaking. Restart your router and check for any unusual settings.
  • DNS Settings: Modify DNS settings to use reliable DNS services which can resolve secure connections more effectively.

4. Browser-Specific Solutions

  • Clear Cache and Cookies: Clear your browser's cache and cookies to remove any outdated security certificates.
  • Update Browser: Ensure that Safari or your browser of choice is updated to its latest version.

5. Test on Different Devices and Networks

  • Different Device Testing: Test accessing the website from different devices to see whether the issue is specific to one device.
  • Different Network Testing: Try accessing your website through different networks (e.g., mobile data vs. WiFi) to determine if your network might be causing the problem.
