What "Your Connection Is Not Private" means and why you see it
When your browser shows "Your connection is not private," it is warning you that the encrypted tunnel between your device and the website is broken or missing. The website's security certificate — the digital proof that you are talking to the real website and not an imposter — either does not exist, has expired, or does not match the web address you typed.
This is a real warning, not a false alarm. Your browser is designed to stop you from sending passwords, credit card numbers, or personal information over an unencrypted connection where someone else could read it. The warning appears because something in the chain of trust has failed, and your browser will not pretend it has not.
The cause is usually one of four things: your device's date and time are wrong, your internet connection is being intercepted, the website itself has a certificate problem, or your antivirus or network is blocking the real certificate. Each one has a different fix.
Key Takeaways
- Check your device's date and time first — an incorrect system clock is the most common cause and the easiest to fix.
- If the date is correct, the website's certificate may be expired or misconfigured, which means the website owner needs to fix it, not you.
- Antivirus software, firewalls, or network filters can intercept certificates and trigger the warning even on legitimate sites.
- You can usually proceed past the warning if you trust the site, but never ignore it on banking sites, email, or anywhere you enter passwords.
Check your device's date and time first
Your device's system clock is part of how your browser verifies a website's certificate. If your date or time is wrong by more than a few minutes, the certificate will appear invalid even if the website is legitimate. This is the most common cause and the fastest to fix.
On Windows: Right-click the time in the bottom right corner of your screen and select "Adjust date and time." Check that the date, time, and time zone are all correct. If they are wrong, click "Set time automatically" to let Windows sync with a time server. Restart your browser after the change.
On Mac: Click the Apple menu, go to "System Settings," then "General," then "Date & Time." Make sure "Set date and time automatically" is turned on. If it is already on but the time is still wrong, turn it off and back on again. Restart your browser.
On iPhone or iPad: Open Settings, tap "General," then "Date & Time," and make sure "Set Automatically" is on. On Android, open Settings, tap "System," then "Date and time," and turn on "Automatic date and time."
Understand what the warning is actually telling you
The warning message usually includes one of three specific problems. "The certificate is not trusted" means the website's security certificate comes from a source your browser does not recognize. "The certificate has expired" means the website owner did not renew it. "The certificate does not match the domain" means the certificate was issued for a different website address than the one you are visiting.
If the date and time are correct and you still see the warning, the problem is on the website's side. The website owner needs to install or renew their certificate. You can contact them to report it, but you cannot fix it yourself.
Some browsers show a button that says "Advanced" or "Details." Click it to see the exact problem. This information helps you decide whether to proceed or leave the site.
Check whether antivirus or network software is intercepting the connection
Antivirus programs, firewalls, and network filters sometimes intercept all encrypted traffic to scan it for threats. When they do, they insert their own certificate between you and the website. Your browser sees this fake certificate and shows the warning, even though the website itself is legitimate.
If you see the warning on multiple websites at once, or on sites you know are legitimate (like your bank or Gmail), your antivirus or network is likely the cause. Check whether your antivirus software has a setting for "HTTPS scanning," "SSL inspection," or "encrypted traffic scanning." Turning this off usually fixes the problem, though it means your antivirus cannot scan encrypted traffic.
If you are on a work network or school network, the network administrator may be filtering all traffic. Contact your IT department and ask whether they are intercepting HTTPS connections. If they are, they can add the site to an exception list or provide you with a certificate to install.
Decide whether it is safe to proceed past the warning
Your browser will usually let you click "Advanced" or "Proceed Anyway" to visit the site despite the warning. Whether you should depends on what the site is and what you plan to do there.
Never proceed on banking sites, email, shopping sites where you will enter a password, or anywhere you plan to enter payment information. If your bank's website shows this warning, do not log in. Close the tab and contact your bank directly by phone to report it. A legitimate bank will never ask you to ignore a certificate warning.
You can usually proceed safely on informational sites where you are not entering any personal information — a news site, a blog, a public forum. The risk is that someone could be reading what you see, not that they could steal your password. If you are just reading, that risk is low.
If you are unsure, leave the site and come back later. If the warning is gone, the website owner fixed the problem. If it is still there after a few days, the problem is real and the site is not safe to use for anything sensitive.
Clear your browser cache and cookies if the warning persists
Sometimes your browser stores old certificate information that conflicts with the new one. Clearing your cache and cookies can fix this, though it will also log you out of most websites.
On Chrome: Click the three dots in the top right, go to "Settings," then "Privacy and security," then "Clear browsing data." Select "All time" and check "Cookies and other site data" and "Cached images and files." Click "Clear data."
On Safari: Click "Safari" in the menu bar, then "Settings," then "Privacy." Click "Manage Website Data," find the site in the list, and click "Remove." Or go to "History" and click "Clear History," then select "all history."
On Firefox: Click the three lines in the top right, go to "Settings," then "Privacy & Security," scroll to "Cookies and Site Data," and click "Clear Data."
After clearing, close your browser completely and open it again. Try visiting the site in a fresh tab.
Try a different browser or device to narrow down the problem
If you see the warning in Chrome but not in Safari, or on your phone but not your computer, the problem is specific to that browser or device. This usually means antivirus software, a browser extension, or a network setting on that particular device is causing it.
If you see the warning on every browser and every device on the same network, the problem is likely your network connection or internet service provider. If you see it on every device and every network, the website itself has a certificate problem.
Testing on a different device also helps you decide whether to proceed. If the site works fine on your phone but shows the warning on your computer, you know the site is legitimate and the problem is local to your computer.
Frequently Asked Questions
Is it safe to click "Proceed Anyway" or "Advanced"?
It depends on the site and what you are doing. Never proceed on banking, email, or shopping sites where you enter passwords or payment information. On informational sites where you are just reading, proceeding is usually safe. If you are unsure, do not proceed.
Why does my bank's website show this warning?
Contact your bank when ready by phone. A legitimate bank will never ask you to ignore a certificate warning. The warning could mean someone is intercepting your connection, or it could mean your antivirus is blocking the real certificate. Either way, do not log in until you have spoken to your bank.
Can I fix this by restarting my router?
Restarting your router can help if your internet connection is unstable or if your router is caching old DNS information. Unplug your router for 30 seconds, plug it back in, and wait for it to fully restart. Then try the website again. This fixes the problem in about 10 percent of cases.
What if the warning says "NET::ERR_CERT_AUTHORITY_INVALID"?
This means the website's certificate comes from a source your browser does not recognize. The website owner may have used a free or self-signed certificate, or your antivirus may be intercepting the connection. Check your antivirus settings first, then contact the website owner if the warning persists.
Do I need to uninstall my antivirus?
No. You can turn off HTTPS scanning in your antivirus settings without uninstalling it. Look for "SSL inspection," "encrypted traffic scanning," or "HTTPS scanning" in your antivirus settings and turn it off. Your antivirus will still protect you against most threats.
