If Safari can’t open a website
There are several reasons that Safari may not be able to open a website. If you can’t view a website, try these suggestions.
Check the webpage address
Make sure you have the correct address for the webpage and that you typed it correctly.
Try entering “/index.html” at the end of the address.
Empty the cache and reset Safari
To empty the cache, press Control-Alt-E and click Empty. Then press Control-R to reload the page.
If emptying the cache doesn’t work, choose Action menu > Reset Safari and click Reset, and then try again to open the page. (The Action menu is near the upper-right corner of the Safari window, and looks like a gear.)
Note:Resetting Safari deletes your browsing history and other information. To learn more, see:
Check your proxy settings
If your computer or network is protected by a proxy or firewall, be sure your network and Internet settings are correct in the Control Panel. Incorrect settings can prevent Safari from connecting to some websites.
Contact the website’s owner
The webpage may prevent users from accessing the page using Safari. Check with the website owner to find out for sure.
Check to see if the first part of the address, which identifies the Internet protocol (such as http or https), is nonstandard. If it is nonstandard, Safari can’t open it.
Ask the website owner if there’s a problem with the web server’s configuration.
If the webpage still won’t open, report the problem by opening the Action menu near the upper-right corner of the Safari window (looks like a gear) and choosing “Report Bugs to Apple.”
