Safari Can't Open the Page

Hello RungybearsParent,

We would like to see if we can help with Safari. Does Safari become completely unresponsive? Which macOS version are you currently running on your Mac? Are you able to refresh or open a new tab with Command + T on your keyboard? Follow the steps in this link and get back to us: If Safari doesn't open a page or work as expected on your Mac - Apple Support

"Test with a private window 

A website can store cookies, caches, and other data on your Mac, and issues with that data can affect your use of the website. To prevent the website from using that data, view it in a private window: From the menu bar in Safari, choose File > New Private Window, or press Shift-Command-N.

If that works, use the following steps to remove the website's data, including its caches and cookies. The website can then create new data as needed. If it's a website that you sign in to, make sure that you know your sign-in information before continuing.

1. Choose Safari > Settings (or Preferences), then click Privacy.
2. Click Manage Website Data.
3. Select the affected website from the list shown.
4. Click Remove.
5. Click Done.
6. Open the website again in a non-private browser window."

Cheers!
