Apple’s Safari browser is designed to keep users safe online by refusing to load websites that don’t meet its strict security standards. While this is a useful security feature, it can also lead to frustration when you can’t access sites you know and trust.
The “Safari can’t establish a secure connection to the server” error typically appears when the browser can’t verify that the website you’re trying to visit uses proper encryption to protect your data. This encryption is crucial for maintaining your online privacy and preventing unauthorized access to sensitive information like login credentials or financial details.
In this comprehensive guide, we’ll explore the reasons behind this error message and provide step-by-step solutions to help you resolve the issue and continue browsing securely.
Why Does Safari Block Insecure Connections?
To understand why Safari blocks insecure connections, it’s important to know how the browser verifies website security.
When you try to access a website, Safari checks the site’s SSL/TLS certificate to ensure it’s using encryption to protect your data. If the certificate is missing, invalid, or can’t be verified, Safari assumes the connection is insecure and blocks the site to prevent potential threats.
This process is designed to protect you from various risks associated with unencrypted connections, such as:
- Eavesdropping: Attackers can intercept and read your data transmissions.
- Data tampering: Malicious parties can modify the information you send or receive.
- Impersonation: Hackers can pretend to be the legitimate website and trick you into sharing sensitive data.
By refusing to load insecure sites, Safari helps mitigate these threats and ensures your online activities remain private and secure.
Signs of an Insecure Connection in Safari
Before we dive into troubleshooting steps, it’s helpful to understand how Safari indicates whether a connection is secure or not. You can check the security status of a website by looking at the URL bar in Safari:
- Green padlock icon: This means the website has an extended validation certificate and is highly secure.
- Grey padlock icon: The site has a standard SSL/TLS certificate and the connection is secure.
- No padlock icon: The website doesn’t have a valid certificate, so the connection is insecure.
If you see the “Not Secure” label or get a certificate warning when trying to access a site, it’s a clear sign that Safari considers the connection insecure and won’t load the page.
Troubleshooting Steps to Fix the “Safari Can’t Establish a Secure Connection” Error
Now that you understand why Safari blocks insecure connections, let’s go through various troubleshooting steps to resolve the “Safari can’t establish a secure connection to the server” error.
1. Verify the URL
Sometimes, the issue could be as simple as entering the wrong URL or visiting a malicious site designed to look like a legitimate one. Double-check the website address in the URL bar to ensure you’re accessing the correct site.
If you’re unsure of the correct URL, perform a web search for the site and click on the official result to access it safely.
Besides, if you are bothered with the errors like preventing cross-site tracking on browsers and phones, or err_connection_reset on Chrome, here are the top solutions for you.
2. Check Your Date and Time Settings
Having the wrong date and time on your device can prevent Safari from properly verifying website certificates, leading to the secure connection error. To fix this:
- On Mac: Open System Preferences > Date & Time, unlock changes, and enable “Set date and time automatically.“
- On iPhone/iPad: Go to Settings > General > Date & Time and turn on “Set Automatically.“
3. Change Your DNS Server
Issues with your device’s DNS (Domain Name System) settings can also cause problems establishing secure connections. Try changing your DNS server to a public one, like Google’s:
- On Mac: System Preferences > Network > Advanced > DNS, and add Google’s DNS servers: 8.8.8.8 and 8.8.4.4.
- On iOS: Settings > Wi-Fi > (Your Network) > Configure DNS > Manual, and add the Google DNS servers.
4. Trust the Website in Your Antivirus Software
If you’re using antivirus software on your Mac, it may be blocking certain websites and causing the secure connection error. Add the problematic site to your antivirus’ list of trusted websites to resolve this.
5. Trust the Website Certificate in Keychain Access
Safari may not trust the SSL/TLS certificate used by the website you’re trying to access. To fix this:
- Use another browser (like Chrome or Firefox) to view the site’s certificate details.
- Open Keychain Access on your Mac and find the certificate in the System Roots > Certificates section.
- Double-click the certificate, expand the “Trust” section, and set “When using this certificate” to “Always Trust.”
6. Disable IPv6 on Your Network Connection
Some websites still use the older IPv4 protocol, which can cause conflicts with the newer IPv6 and lead to connection issues. Try disabling IPv6 temporarily on your Mac:
- System Preferences > Network > (Your Wi-Fi Network) > Advanced > TCP/IP
- Configure IPv6 to “Manually” and click OK.
7. Use a VPN for Enhanced Security
If you frequently encounter secure connection errors, consider using a reputable VPN service. A VPN encrypts your internet traffic, effectively creating a secure tunnel between your device and the websites you visit.
This added layer of encryption can help bypass many website security measures and ensure your online activities remain private, even on public Wi-Fi networks.

- Check for issues with the website URL, date/time settings, DNS configuration, antivirus software, and website certificates.
- If the problem persists, try disabling IPv6 or using a VPN for enhanced security.
- Building a secure browsing environment is crucial for maintaining your online privacy and safety.
FAQs
Q: Will updating Safari fix the “can’t establish a secure connection” error?
A: Keeping Safari up-to-date is generally a good practice, as new updates often include security enhancements and improved compatibility with modern websites. However, updating alone may not resolve the error if the underlying issue is related to your network, device settings, or the website itself.
Q: Can disabling extensions in Safari help?
A: Yes, disabling extensions or plugins in Safari can sometimes resolve secure connection issues caused by conflicts or compatibility problems. Try disabling extensions one by one to identify if any of them are causing the error.
Q: What should I do if none of these troubleshooting steps work?
A: If you’ve tried all the recommended troubleshooting steps and are still experiencing the “Safari can’t establish a secure connection” error, your best course of action is to contact your internet service provider or network administrator. They can further diagnose and assist with resolving any network-related issues that may be causing the problem.
Q: Is it safe to proceed with an insecure connection in Safari?
A: No, it’s generally not recommended to proceed with an insecure connection in Safari, as it puts your data at risk of being intercepted or compromised.

If you absolutely must access a particular website, consider using a VPN or another secure browsing method.
Q: Can I manually trust a website’s certificate in Safari?
A: Yes, you can manually trust a website’s certificate in Safari by adding it to the Keychain Access application on your Mac. However, this should only be done for websites you absolutely trust, as it essentially bypasses Safari’s security measures for that particular site.
