Safari cannot open the page because the address is invalid.

The error message "Safari cannot open the page because the address is invalid" usually means that the web address (URL) you are trying to access is not correct or does not exist.

1. Check the URL: Make sure that the URL you entered is correct and doesn't have any typos or errors. Try typing the URL again to see if it works.
2. Check your internet connection: Make sure that you have a stable internet connection. You can try restarting your router or modem to see if it helps.
3. Clear your browser cache: Sometimes, a corrupted or outdated cache can cause issues with web pages. Try clearing your browser cache and then reloading the page.
4. Check if the website is down: The website you're trying to access may be down or experiencing issues. You can check the website's social media pages or use a website status checker to see if the site is working.

If none of these solutions work, you may want to contact the website's support team (Not Safari) for further assistance.
