How to fix cannot establish secure connection error in Safari

The suffocating feeling that someone looks over your shoulder is quite uncomfortable. The same is replicated by the nasty ad trackers who track your browsing activities and how you use content. As much as I want to not joke, you need to be aware of what really happens to your favorite sites.

Fortunately, Apple crac King is down to the scary sites that track your behavior, whether or not you click on their site. In addition, Apple's latest version of Safari includes Intelligent Tracking Protection 2.0, which examines and defends third parties as well as first-party potentials to track your browsing activities.

Therefore, Safari may fail while opening a suspicious or improperly crafted page. If you've met the "Cannot establish secure connection" error message with your frequently visited sites, you're not alone. Here are the best work solutions to help you fix that error and continue to surf peacefully.

1. Check for the correct certificate

To keep it simple, make sure you access the right site by clicking on the address bar. You should examine the URLs and look for the green lock icon in front of the site address. If it looks like gray, it may be a cleverly crafted phishing site with the exact logo and layout of your bank or another site you visit frequently.

2. Delete Browser History

The Safari option to delete the browser log is like a double-edged sword. Usually, the Clear Browser History option will remove the list of sites you visited. However, the latest iteration of Safari removes the related data, such as cookies and content on the respective sites. [19659000] “/>  Step 1: </strong> In Safari, click History to create the menu options at the top of the window. </p>

3. Uninstall Suspicious Extensions and Plugs

Extensions, plugins and add-ons are like little helpers that speed up the process of performing specific tasks with a click or two. However, installing for many of them affects Safari's performance. So, it is only wise that you remove the unwanted and unused plugins or extensions.

Step 1: Click the Safari menu and select Settings.

  Step 1 Uninstall Plugins Add Our Safari Macos "width =" 543 "height =" 299 "data-sizes =" auto "size =" (min width: 976px) 700px (min width: 448px) 75vw, 90vw "srcset =" https://cdn.guidingtech.com/imager/media/assets/2019/07/231801/Step-1-Uninstall-plugins-add-ons-safari-macos_4d470f76dc99e18ad75087b1b8410ea99 .png? 1563024455 543w, https: //cdn.guidingtech.com/imager/media/assets/2019/07/231801/Step-1-Uninstall-plugins-add-ons-safari-macos_40dd5eab97016030a3870d712fd9ef0f.png?1563024455 500w, https : //cdn.guidingtech.com /imager/media/assets/2019/07/231801/Step-1-Uninstall-plugins-add-ons-safari-macos_7c4a12eb7455b3a1ce1ef1cadcf29289.png?1563024455 340w

Step 2: From the pop-up window, click Extensions to display the list of extensions you have installed for Safari. I didn't install any extensions. But if you see something, select and remove them.

4. Unblock All Cookies

It may be an honest mistake that you accidentally click on the box that appears just below the one that says – Prevent cross-site tracking. If this is the case, the box essentially blocks all cookies.

Step 1: Open Safari preferences and click Privacy.

Then you can select and remove the cookies on the sites you think you no longer need or want.

Check Permissions

In addition to overboard plug-ins, some of them force to block content blocks for known sites to carry unwanted pop-ups and misleading ads with some code on them. If you believe that Safari hits a false positive, better check the permissions for the content blocks and other items like Place.

Step 1: Click the Safari menu and select Settings. From the window that appears, click on the Websites tab.

 Step 1 Check permissions Safari Macos "width =" 508 "height =" 302 "data-size =" auto "sizes =" (min width: 976px) 700px, (min width: 448px) 75vw, 90vw "srcset =" https://cdn.guidingtech.com/imager/media/assets/2019/07/231806/Step-1 -Control-Permissions-Safari-macos_4d470f76dc99e18ad75087b1b8410ea9.png? 1563024457 508w, https://cdn.guidingtech.com/imager/media/assets/2019/07/231806/Step-1-Check-Permissions-Safari-macos_40dd5eab97016030a3870d712fd9ef0f.png? 1563024457 500w, https://cdn.guidingtech.com/imager/media/assets/2019/07/231806/Step-1-Check-Permissions-Safari-macos_7c4a12eb7455b3a1ce1ef1cadcf29289.png?1563024457 340w

Step 2: Click the Content Blocks in the left pane and see if you have blocked a particular item on the site you are trying to access.

Flushing the DNS cache

At times, flushing the DNS cache helps solve many connection and web page speed issues. This solution is quite simple, provided you write the command exactly.

<img class = "lazyload nonjs-hidden" src = "https://cdn.guidingtech.com/imager/media/assets/2019/07/231808/Flush-DNS-Cache_7c4a12eb7455b3a1ce1ef1cadcf29289. png? 1563024458 "alt =" Flush Dns Cache "width =" 732 "height =" 462 "data sizes =" auto "sizes =" (min width: 976px) 700px, (min width: 448px) 75vw, 90vw "srcset =" https://cdn.guidingtech.com/imager/media/assets/2019/07/231808/Flush-DNS-Cache_4d470f76dc99e18ad75087b1b8410ea9.png?1563024457 732w, https://cdn.guidingtech.com/imager/media/assets/2019 /07/231808/Flush-DNS-Cache_935adec67b324b146ff212ec4c69054f.png?1563024458 700w, https://cdn.guidingtech.com/imager/media/assets/ 2019/07/231808 / Flush DNS Cache_40dd5eab97016030a3870d712fd9ef0f.png? 1563024458 500w, https : //cdn.guidingtech.com/imager/media/assets/2019/07/231808/Flush-DNS-Cache_7c4a12eb7455b3a1ce1ef1cadcf29289.png? 1563024458 340w [19659004] Make sure Safari is not running and if it is, exit it Start Terminal the app on your Mac and type the following command:

  sudo killall -HUP mDNSResponder 

You must enter the administrator password and then enter the Enter key. Restart Safari to see if it helped.

7. Firewall settings

Firewall protects you from false requests to steal data and resources. It is possible that some software has enforced strict Firewall policies and excludes Safari from any Internet connection. Well, it happens when parents or office environment do not want you to surf the web. It's a safe way to check if the firewall blocks Safari.

Step 1: Hit Command + Intermediate Keys to launch the Spotlight Search line.

Step 2: Type Firewall in Spotlight Search and press Enter.

Step 3: Click on the lock at the bottom left, enter your system password and press the Unlock button to make changes to the firewall settings. When you access, click the firewall options button.

also check if Safari appears in the exception list and has Allow incoming connections enabled for it. If Safari does not appear there, proceed to the next solution.

8. Synchronizing Your System Time

While it's not likely that your Mac's system time is wrong, it's best to check it once. Here's how to confirm and change system time.

 System Time Settings Changing Safari Mac Os "width =" 670 "height =" 530 "data-sizes =" auto "size =" (min width: 976px) 700px, (min width: 448px) 75vw, 90vw "srcset =" https://cdn.guidingtech.com/imager/media/assets/2019/07/231807/System-Time- Settings-Change-Safari-MacOS_4d470f76dc99e18ad75087b1b8410ea9.png? 1563024458 670w, https://cdn.guidingtech.com/imager/media/assets/2019/07/231807/System-Time-SettingsChange-Safari-MacOS_40dd5eab97016030a3870d712fd9ef0f.png?1563024459 500w, https: //cdn.guidingtech. com / imager / media / assets / 2019/07/231807 / System-Time-Settings-Change-Safari-MacOS_7c4a12eb7455b3a1ce1ef1cadcf29289.png? 1563024459 340w

Click the Apple menu and select System Preferences. From the window that appears, click Date and Time. Then click on the time zone to check if you have selected the correct one. To make some changes, click the lock icon at the bottom left and enter your macOS account password.

9. Remove All Site Data

Apple removed the Reset Safari button since the Yosemite update. Fortunately, there are two easy ways to achieve stock Safari experience.

Step 1: Start Safari, click the Safari menu, and select Settings.

Step 2: Click the Privacy tab from the pop-up window, and then tap the button that says – Manage Site Data.

 Step 2 Reset Safari Settings Mac Os "width =" 776 "height =" 274 "data-sizes =" auto "sizes =" (min width: 976px) 700px (min width: 448px) 75vw, 90vw "srcset =" https://cdn.guidingtech.com/imager/media/assets/2019/07/231797/Step-2-Reset-Safari-settingsmacOS_4d470f76dc99e18ad75087b1b8410ea9.png? 1563024459 776w, https: // cdn.guidingtech.com/imager/media/assets/2019/07/231797/Step-2-Reset-Safari-setings-macOS_935adec67b324b146ff212ec4c69054f.png?1563024459 700w, https: //cdn.guidingtech. com / imager / media / assets /2019/07/231797/Step-2-Reset-Safari-setingsmacOS_40dd5eab97016030a3870d712fd9ef0f.png?1563024459 500w, https://cdn.guidingtech.com/imager/media/assets/2019/07 / 231797 / Step-2 Reset Safari Settings-macOS_7c4a12eb7455b3a1ce1ef1cadcf29289.png? 1563024459 340w

Step 3: Wait for the popup window to fill out the list of sites. Now you can either remove data on selected sites or all. You can also press the Remove All button and clean the data.

 Step 3 Reset Safari Settings Mac Os "width =" 825 "height =" 535 "data-sizes =" auto "sizes =" (min width: 976px) 700px, (min width: 448px) 75vw, 90vw "srcset =" https://cdn.guidingtech.com/imager/media/assets/2019/07/231798/ Step 3-Reset-Safari Settings-macOS_4d470f76dc99e18ad75087b1b8410ea9.png? 1563024460 825w, https://cdn.guidingtech.com/imager/media/assets/2019/07/231798/Step-3-Reset-Safari-Settings-macOS_935adec67b324b146ff212ec4c69054f .png? 1563024460 700w, https://cdn.guidingtech.com/imager/media/assets/2019/07/231798/Step-3-Reset-Safari-Settings-macOS_40dd5eab97016030a3870d712fd9ef0f.png?1563024460 500w, https: // cdn .guidingtech. com / imager / media / assets / 2019/07/231798 / Step 3-Reset-Safari-Settings-macOS_7c4a12eb7455b3a1ce1ef1cadcf29289.png? 1563024460 340w

Performing this solution, along with the first one, should be good enough to set Safari to its factory status. You can exit Safari and restart it to try to access the site that gives you so much grief.

10. Use Another Browser

If nothing works and you need to use a web browser, it's better to use another browser like Firefox or Chrome.

Continue Safe Browsing

If none of the solutions mentioned above work, the problem may be with the site. The installation of macOS is the last resort, and I bet it doesn't. One of the solutions mentioned above should work for your Mac. It is quite possible that the site you are trying to access is not available and is facing downtime.
