What to do if…
your device clock resets and secure websites stop loading correctly

Short answer

Set your device’s date, time, and time zone correctly, preferably using automatic time settings, then restart the browser and try again. Do not bypass certificate or security warnings while the clock is wrong.

Do not do these things

Do not click through certificate warnings such as “Your connection isn’t private,” “Secure connection failed,” or “Your clock is ahead” just to reach a login page.
Do not enter passwords, banking details, work credentials, or verification codes on any page showing a security warning.
Do not install “certificate fix,” “clock fix,” or “browser security fix” tools from pop-ups, ads, emails, or unknown sites.
Do not change several things at once, such as VPN, proxy, DNS, antivirus HTTPS scanning, certificates, and browser settings; it makes the problem harder to undo.
Do not factory reset the device as a first step.

What to do now

Pause sensitive logins. Use a different trusted device for email, banking, password managers, work accounts, or account recovery until this device’s clock is correct and secure websites load normally.
Set the date, time, and time zone to automatic where possible.
- Windows: Settings → Time & language → Date & time → turn on Set time automatically and Set time zone automatically if available. Use Sync now if it appears.
- Mac: System Settings → General → Date & Time → turn on Set time and date automatically and Set time zone automatically using your current location.
- iPhone or iPad: Settings → General → Date & Time → turn on Set Automatically.
- Android: Open the Clock app or device settings for date and time, then turn on Automatic date and time and Automatic time zone if your device offers them. Wording varies by manufacturer.
Check the obvious details before testing again. Confirm the year, month, day, time, AM/PM, and time zone are right for where you are now.
Restart the browser. Close all browser windows, reopen the browser, and try one secure site you trust by typing its address yourself.
Restart the device if the error remains. After restarting, check the clock again before opening email, banking, work, or password manager sites.
Try a different network. Use a mobile hotspot or another Wi-Fi network if you can. If secure sites work on another network, the issue may involve the original Wi-Fi, router, DNS, filtering, or a captive portal sign-in page.
Turn off only the network security setting you control, then test once. On your own personal device, you can briefly turn off a VPN, proxy, or HTTPS scanning feature you intentionally installed. Change one setting only, test, then turn protection back on unless you are sure it caused the problem. For a work, school, or managed device, ask IT instead.
Update the browser and operating system from built-in settings. Use the device’s normal update screens, not pop-ups or third-party “fix” downloads.
If the clock resets again after power-off or restart, treat it as a persistence problem. The device may have a hardware, firmware, battery, or time-sync issue. Keep using a different trusted device for sensitive accounts until the clock stays correct.
If you already entered credentials while a warning was showing, switch to a trusted device. Change the affected password, sign out of other sessions if the account offers that option, and turn on multi-factor authentication if it is not already on.
If money was taken, accounts were accessed, or you suspect a scam, use official routes typed directly into the address bar. In the USA, scams and fraud can be reported to the FTC, and cyber-enabled crime can be reported to the FBI’s IC3.

What can wait

You do not need to diagnose whether the cause is hardware, malware, browser settings, network filtering, or a time server before you fix the clock and avoid unsafe logins.
You do not need to replace parts, reinstall the operating system, reset the browser, or factory reset the device right now.
You do not need to report anything before you are using a trusted device, unless money is actively being moved or an account is actively being used without permission.

Important reassurance

This can look alarming, but secure websites rely on your device’s clock to check whether certificates are valid. When the clock is wrong, browsers may correctly block secure pages to protect you.

Scope note

These are first steps to regain safer access and avoid credential theft. If the clock will not stay correct, or if this is a managed work or school device, later decisions may need help from IT support, the device maker, your employer, or another qualified specialist.

Important note

This is general information, not professional IT, legal, financial, therapeutic, or security advice. For suspected fraud, account compromise, or device tampering, use a trusted device and official support channels rather than links from pop-ups, emails, ads, or warning pages.
