Troubleshooting a Persistent “Your Connection is Not Private” Error

Hello Readers,

As someone with nearly three years of experience in tech support, I pride myself on my problem-solving skills. However, a recent technical hiccup has left me quite bewildered, and I’m reaching out for your insights.

I’ve encountered a frustrating scenario while using my Ethernet connection, where every time I attempt to access any website, I am met with the following error message:

“Your connection is not private”

The warning further alerts me that attackers might be attempting to steal sensitive information, such as passwords or credit card details, and indicates an NET::ERR_CERT_COMMON_NAME_INVALID issue.

To tackle this problem, I’ve already undertaken a variety of troubleshooting steps:

1. Adjusted date and time settings
2. Cleared cache and cookies, and attempted browsing in Incognito mode
3. Tried different web browsers
4. Executed a Winsock reset and DNS flush
5. Restarted the router and switched Ethernet ports (noting that I am the only Ethernet-connected PC in the house)
6. Manually configured my IP and DNS settings
7. Verified the proxy settings
8. Cleared the SSL state
9. Reinstalled the network drivers
10. Attempted to add “-ignore-certificate-errors” to my Chrome shortcut
11. Disabled my antivirus software and turned off Windows Defender

My current setup consists of a PC connected directly to the router with the following specifications:
– Motherboard: Asus B450-F Gaming
– CPU: Ryzen 2700X
– Operating System: Windows 10 x64, version 1809
– GPU: Gigabyte RTX 2080

Despite my best efforts, this issue persists. If anyone has encountered a similar problem or has suggestions for additional troubleshooting, I would greatly appreciate your guidance!

Update: Resolution
After much trial and error, I managed to resolve the issue by flashing the router to the latest firmware and resetting it to factory settings. If you’re experiencing similar difficulties, consider this as a potential solution!
