Many users face the problem “Microsoft Edge can’t connect to this page safely” after Windows 10 Fall Creators Update (v1709) or Creators Update (v1703). An error message “Can’t connect to this page securely” appears on the screen, preventing you from opening the web page.
Except Microsoft Edge, the error also appears in other browsers such as Google Chrome, Internet Explorer, FireFox, etc. This may be caused by outdated or unsafe TLS settings or caused by tampering with the network driver or other network-related settings.
Today, this Windows 10 guide will show you two basic troubleshooting methods “Microsoft Edge can’t connect to this page securely” on a Windows 10 computer:
Reasons for this site use outdated or insecure TLS security settings
If this error occurs, there may be several reasons (and fixes). Brief description:
- The website uses older TLS encryption settings (e.g. 1.0 or 1.1) and you made the settings accept only TLS 1.2 or higher.
- The website only uses TLS 1.2, but you have disabled TLS 1.2 in your Internet settings or: You have an older operating system that (for now) does not support TLS 1.2.
- The website supports the HTTPS protocol but it also has some HTTP elements (like external images).
- You (or your company’s system administrator :)) have disabled the use of weak MD5 and 3DES encryption algorithms
Enable TLS protocols
If a website is unable to connect safely, the most common reason is the incorrect configuration of TLS protocols. These protocols are enabled by default in Windows. However, an error may occur if third-party software or users have disabled the protocols.
So make sure that TLS 1.0, TLS 1.1 and TLS 1.2 are enabled.
Step 1: Enter the Internet settings in the search box and click it.
Step 2: After opening the Internet properties, go to the “Advanced” section and make sure that these check boxes are checked. Use TLS 1.0, use TLS 1.1 and use TLS 1.2.
Step 3: Make sure that the Use SSL 3.0 option is unchecked, as it can cause problems and make things worse.
Step 4: Save the changes.
Reset Internet Explorer settings
We recommend that you clear cache and cookies in Microsoft Edge and reset Internet Explorer settings.
How to clear cache and cookies in Microsoft Edge:
- Open Microsoft Edge.
- Click on the three horizontal dots in the upper right corner of the window.
- Click “Settings”.
- In the “Clear preview data” section click “Select what to delete”.
- Make sure that your browsing history, cookies, and saved website data, as well as cached data and files, are enabled, then click Delete.
To reset your Internet Explorer settings:
- Open Run by pressing the Windows + R key.
- In the Run field, type inetcpl.cpl and click “OK”.
- In Internet properties, click Advanced.
- In the section “Reset Internet Explorer settings” click “Reset”.
- Click on Reset
- Close the window and reboot the computer.
Enable mixed content
If the website you visit has mixed HTTP and HTTPS content, IE or Microsoft Edge will not be able to securely connect to this page. In this case you need to enable the “Show mixed content” option to solve this problem.
To do this, follow this instruction:
Step 1: Also open the Internet Properties window by searching the Internet settings.
Step 2: On the “Security” tab, click “Other”, scroll down, find “Show mixed content” and select “Enable”.
Step 3: Click OK to save your changes.
