If you are getting errors such as “Your connection is not private,” “This site can’t be reached,” NET::ERR_CERT_DATE_INVALID, NET::ERR_CERT_AUTHORITY_INVALID, DNS_PROBE_FINISHED_NXDOMAIN, ERR_CONNECTION_RESET, ERR_CONNECTION_TIMED_OUT, or other Chrome and internet connection errors, try the following methods one by one. These steps cover common problems related to date and time, VPN, browser security, SSL, DNS, Windows network settings, and security software.
1. Set the Correct Date and Time
An incorrect date, time, or time zone can cause SSL and certificate errors such as NET::ERR_CERT_DATE_INVALID and Your connection is not private.
Open Settings → Time & language → Date & time.
Turn on Set time automatically and Set time zone automatically. Then click Sync now under Additional settings.
After synchronizing the date and time, reopen Chrome and check whether the website works.
2. Disable VPN
If you are using a VPN, it can sometimes interfere with DNS resolution, website connections, or SSL certificates.
Temporarily disconnect your VPN and try opening the website again.
If the website works after disabling the VPN, the VPN connection or its configuration may be causing the problem. You can then reconnect the VPN and check its settings or try another server.
3. Check Chrome Security and Change DNS
Open Chrome and go to Settings → Privacy and security → Security.
For troubleshooting, you can temporarily select No protection (not recommended) and test the website. This should only be used briefly for testing because it reduces Chrome's security protection.
You can also check the Use secure DNS option and change the DNS provider if necessary.
After the website starts working, restore Chrome's security setting to its default/recommended protection. Do not leave Chrome set to No protection for normal browsing.
4. Clear the SSL State
Windows stores SSL connection information that can sometimes cause certificate-related problems.
Press Windows + R, type:
inetcpl.cpl
and press Enter.
Open the Content tab and click Clear SSL state.
Click OK, restart Chrome, and try opening the website again.
5. Reset DNS and Windows Network Settings Using Command Prompt
Network configuration problems can cause errors such as ERR_CONNECTION_RESET, ERR_CONNECTION_TIMED_OUT, DNS_PROBE_FINISHED_NXDOMAIN, ERR_NETWORK_CHANGED, and ERR_NAME_NOT_RESOLVED.
Open Command Prompt as Administrator and run these commands one bye one :
ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset
After restarting, try opening the website again.
6. Temporarily Disable Real-Time Protection
Sometimes security software can interfere with HTTPS connections or block certain network connections.
If you suspect Windows Security is causing the problem, you can temporarily test the connection by going to Windows Security → Virus & threat protection → Manage settings and temporarily turning off Real-time protection.
Test the website immediately after disabling it.
If the website works, turn Real-time protection back on and investigate the security software or its web/network protection settings. Do not leave real-time protection disabled during normal use.
7. Change DNS to Google DNS
If the problem is related to your current DNS server, changing DNS can help resolve website and DNS-related errors.
Use Google's public DNS:
Preferred DNS: 8.8.8.8
Alternate DNS: 8.8.4.4
In Windows 11, go to Settings → Network & internet → Wi-Fi or Ethernet → Hardware properties → DNS server assignment → Edit.
Select Manual, enable IPv4, enter the two DNS addresses, and save the settings.
Then restart Chrome and test the website.
Final Step
After completing these methods, restart your computer and test the problematic website again. These troubleshooting steps can resolve many common DNS, network, SSL, certificate, proxy, and browser connection problems.
However, if the error occurs only on one particular website, the problem may be with that website's SSL certificate or server configuration, and changing settings on your computer may not fix it.
