Your connection is not private

i have an iphone 7, when i try to connect to a web site I get a your connection is not private message. I have a work iphone & ipad that connect with no issue. All have same version Ios. Happens with safari too.

Ive tried removing chrome, connecting through a vpn & hotspot with no luck. Any ideas?

The reason will be in the difference between the error producing iPhone and the other devices.

- Date & Time / Time Zone setting is individual to each device. Settings > General > Date & Time > Automatically + correct time zone.

- Browser cache/Website Data is individual to each device. Settings > Safari > Clear History & Website Data (or Advanced > Website Data > Edit > { ➖ select specific site} )

- (Third party) software that may interfere with secure connections will have settings individual to each device. Only you know what you have installed.

- Some other difference that only you know about.

“Your connection is not private” is a Chrome wording of the failed security check on the site certificate.


The issue could be about https vs. http, or similar Transport Layer Security URL. Unless it is your own bookmark (you could use http instead, without the expectation of security), there is little you can do about it. Often it is something the site owner must do to fix it (Revoked certificate/old certificate; Mix of https and http in a single webpage; etc.).


Other reasons for a failed secure connection between the user and the server:

  1. If time and date are off too much, the security check of the certificate will fail. Set the time correctly.
  2. 3rd party “security” monitoring software (anti malware, anti virus, privacy, etc.) may reject a secure connection on wrong assumptions or settings. Don’t use such software.
  3. Browser caches/Website Data could be a cause for disrupted functionality. Removing such data may fix that.
  4. Not the latest version of the software. Relaunch with updated version of the app, to get the latest security fixes.
  5. A VPN tunnel may be misunderstood by some of the components as a MITM.


And lastly, there is a choice to bypass it, if you are confident that the message is not describing a thread in your situation (Advanced > Continue to site). Generally not recommended!

I still don’t understand why can I still access the site on my pc, iPad & iPhone 6s, my wifes iPhone 7- just not this single iPhone 7 - (Both Chrome & Safari)


NET::ERR_CERT_INVALID is the error.


If it's a certificate error - why doesn't Chrome & Safari stop me accessing the site from all other devices?


Advanced doesn't give me the option to continue on my phone like it does occasionally on my pc.
