By following these steps you can fix safari:
- Clear the Data in Your Browser- As a result, clearing your browser cache is one of the quickest and easiest ways to repair this error. To do so in Safari, start by launching the application.Then go to Preferences > Privacy and choose Remove All Website Data. After that, go to Safari > History > Remove History to clear your full browsing history.
- Change Your DNS Configuration-If your DNS settings are incorrect, you may receive the message 'Safari can't create a secure connection to the server.' You can try altering your DNS addresses to see whether this is the case (and if so, how to fix it). You might, for example, utilise Google's Public DNS. To begin, go to Apple > System Preferences.>Network.
