If Safari can't open the page because too many redirects occurred
This might occur when you open a page that is redirected to another page, which is then redirected to open the original page.
If a webpage redirects too many times, it might have been set up in a way that is causing a redirect loop. In that case, the owner of the page will need to correct the issue.
The issue might also relate to outdated redirect information in your browser cache or cookies. To find out:
From the menu bar in Safari, choose Safari > Preferences, then click Privacy.
Click Manage Website Data.
Use the Search field to find the name of the redirecting website, then select the website and click Remove. Safari then removes all stored data for the website, including caches and cookies. This might sign you out of the website or change its behavior.
Click Done, then close Safari preferences.
If the issue continues, repeat these steps, but instead of clicking Remove for the redirecting website, click Remove All to remove stored data for every website you've visited in Safari.
