It might be annoying to get an error message like "Safari can't establish a secure connection" when surfing the internet. You can't access certain websites because of this difficulty, which often results from security-related issues. In this post, we'll look at some of the potential reasons for this mistake and provide you with some troubleshooting advice to help you fix it. So let's get started and fix your Safari browser!

Understanding the Error

Safari normally displays the error message "Safari can't establish a secure connection" when it is unable to connect securely and encrypted to the website you are attempting to view. This occurs when the security certificate for the website is not valid, has expired, or does not match the domain you are now viewing.

Check Your Internet Connection

Make sure your internet connection is reliable before moving on to more difficult troubleshooting techniques. A shaky or erratic connection may hinder the secure connection process. In order to rule out any network-related difficulties, restart your router or attempt to connect to a new network.

Update Safari

It's critical to keep your Safari browser updated for maximum speed and security. Older browser versions may not have the required protocols for creating secure connections. On macOS, click the Apple menu, pick "System Preferences," and then choose "Software Update." When using an iOS device, go to "Settings," press "General," and choose "Software Update."

Delete All Cookies and Cache

Safari employs cache and cookies, which are saved pieces of data, to speed up surfing and remember website settings. However, a buildup of stale or damaged data may cause connectivity problems. Such issues may often be fixed by clearing the cache and cookies in your browser. Go to the "Safari" menu, click "Clear History," and then choose the right time frame to do this on Safari.

Turn off Extensions

Secure communications may sometimes be hampered by browser plugins and extensions. Disable any installed extensions momentarily, then attempt to view the website once again. If the issue goes away, you may find the problematic extension by disabling each one one at a time until the issue recurs.

Modify the Time and Date Settings

Your device's incorrect date and time settings may result in security certificate problems that hinder secure connections. Make sure that the time, date, and time zone settings on your device are correct. Go to the "Apple" menu on macOS, click "System Preferences," then pick "Date & Time." When using iOS, go to "Settings," hit "General," then choose "Date & Time."

Turn off any security software

Firewalls or third-party security software may sometimes prevent Safari from establishing a secure connection. Disable any firewalls or security programs momentarily, then attempt to visit the website once again. If the issue is resolved, you may need to modify the security software's settings to enable Safari to create secure connections.

Verify the website's SSL certificate and URL

Check your URL again if you get an error notice on a certain website. Make sure you spelled it properly, paying attention to the "https://" prefix. Verify the website's SSL certificate as well. Proceed with care and refrain from entering any personal or sensitive information if the certificate looks invalid or expired.


The "Safari can't establish a secure connection" problem might be annoying, but you can fix it by using the troubleshooting advice in this article. Don't forget to check your internet connection, update Safari, delete cache and cookies, temporarily turn off extensions, change the date and time settings, and turn off any disruptive security programs. You'll have a better chance of re-establishing secure connections and getting a flawless Safari surfing experience if you adhere to these instructions.
