Safari Connection Not Private: Fix It on iPhone, iPad & Mac

To fix Safari’s “This Connection Is Not Private” warning on an iPhone, iPad, or Mac, first check the device’s date and time, then reload the page and test another network. If the warning remains, investigate the website address, VPN or network settings, and Safari data—but do not enter passwords or payment details or bypass the warning unless you can verify the site and understand the risk.

What the warning means

Safari shows this warning when it cannot establish a trusted, encrypted connection to a website. Most commonly, the site’s security certificate is expired, misconfigured, issued for a different domain, or not trusted by the device. A device clock that is substantially wrong can also make a valid certificate appear expired or not yet valid.

The warning is not proof that a site is malicious, but it is a reason to pause. Certificates help Safari check that a connection is encrypted and that the site is presenting credentials for the address you requested. A warning can result from a website’s configuration, a captive public Wi-Fi sign-in page, or something on your device or network interfering with the connection.

Try these checks first

Confirm the address. Check for a typo and make sure you are using the intended domain. Avoid following a suspicious link; instead, navigate to the organization’s known address yourself.
Check date and time. On iPhone or iPad, open Settings > General > Date & Time and turn on Set Automatically if available. On Mac, open Apple menu > System Settings > General > Date & Time and enable automatic setting. Menu wording can vary by system version.
Reload and reopen Safari. Close the affected tab, open a new one, and try again. If the page is important, note the exact warning and address before changing settings.
Test another website. If several unrelated sites show the same warning, the issue is more likely to involve the device, network, or a shared configuration than one website.
Switch networks. Try cellular data on an iPhone or iPad, or a different trusted Wi-Fi network. If the page works elsewhere, the original network may be intercepting traffic, requiring a sign-in, or having a configuration problem.

Check Wi-Fi, VPN, and network filters

Public Wi-Fi sometimes requires you to accept terms or sign in before providing normal internet access. Open a new Safari tab and visit a familiar, non-sensitive website to see whether a network sign-in page appears. Complete the sign-in only if you recognize the network and the page is expected. Do not submit confidential information to an unfamiliar page that appears unexpectedly.

A VPN, content filter, security app, proxy, or managed-device profile can also affect connections. If you use one, check its settings or temporarily disconnect it only when appropriate and permitted by your organization. Then reload the site. If that changes the result, ask the service provider or device administrator for help rather than removing work or school settings.

Restarting the device and router can clear a temporary connection problem. On a Mac, you can also try another browser as a comparison: if the same certificate warning appears there, that points toward the site or network, though it does not establish that the connection is safe. Keep macOS, iOS, or iPadOS up to date through the device’s Software Update settings; updates can include security and trust changes.

Clear Safari data when the problem is isolated

If the warning affects one site but the address, clock, and network appear correct, stale site data may be worth clearing. On iPhone or iPad, go to Settings > Apps > Safari, then use Clear History and Website Data. On some system versions, Safari appears directly in Settings rather than under Apps. Clearing this data can sign you out of websites and remove browsing history or stored site information, so use it with that consequence in mind.

On Mac, open Safari and choose History > Clear History, then select an appropriate time range. You can also manage individual website data in Safari’s settings under Privacy. The available controls and labels can differ between macOS versions. Clearing data cannot repair an expired certificate on the website; if other devices and networks show the same warning, the site owner likely needs to fix it.

When not to bypass the warning

Safari may offer a way to view details or continue, but doing so does not repair the certificate or make the connection trustworthy. Avoid continuing on pages for banking, email, shopping, work accounts, or any service where you would enter a password, payment information, or personal details. Do not install a certificate or configuration profile just because a pop-up or website tells you to.

A limited exception may be a known internal website managed by your employer or school, where an administrator has explicitly explained the certificate setup and provided a supported fix. Verify the instructions through a separate trusted channel. For an ordinary public website, wait and contact its owner or support team if the warning persists. A certificate warning on only one site, across multiple devices and networks, is especially strong reason to report it to that site.

Common causes and what the pattern suggests

One site, all devices: The site may have an expired, mismatched, or incorrectly configured certificate.
Many sites, one network: Check Wi-Fi sign-in, router settings, VPNs, proxies, and network filtering.
Many sites, one device: Check date and time, software updates, VPN or filter settings, and device management.
Only a public hotspot: The connection may need a captive-portal sign-in, or the hotspot may not be trustworthy.

These are clues, not definitive diagnoses. A certificate error can have several causes, and the exact wording in Safari helps distinguish them. If a warning appears on a site that handles sensitive information, stop and contact the site through a known phone number or address rather than using links shown on the warning page.

Frequently Asked Questions

Why does Safari say “This Connection Is Not Private” on every website?
Check the device’s date and time first, then try a different network and review VPN, proxy, or filtering settings. If it continues across networks after a restart and update, contact Apple Support or your device administrator.

How do I fix the warning on my iPhone or iPad?
Verify the website address, set date and time automatically, reload Safari, and test cellular data or trusted Wi-Fi. If only one site is affected, clearing its Safari data may help, but the site owner may need to repair its certificate.

Why does the warning appear on public Wi-Fi?
The hotspot may require a sign-in or terms acceptance, or it may be interfering with secure traffic. Use a trusted network when possible, and do not enter sensitive details into an unfamiliar sign-in page.

Is it safe to tap “Show Details” or continue?
Viewing details is different from trusting the site. Continuing can expose information to an untrusted connection, so do not do it for passwords, payments, email, or other sensitive activity.

Will clearing Safari history fix the warning?
It can help with certain device-specific or stale-data problems, but it cannot fix a website’s expired or misconfigured certificate. Clearing history and website data may also sign you out and remove stored site information.
