Trouble Shooting:"Could not open the page, too many redirects"

Problem:

"Could not open the page, too many redirects"

Solution:

This issue is typically caused by the website you're trying to view, not by Safari. Safari may be able to open the website at a later time, when the website's redirect problem has been corrected.

Occasionally, the issue might be caused by an interaction with Safari. The issue may also occur because redirect information has been retained beyond its useful life.  In some cases, resetting Safari may allow you to regain access to a website. To do that, follow these steps:

1. Setting > Safari
2. "Clear cookies and Data" and "Clear History."
3. in privacy section see "accept cookies" and select "from visited"

If the issue persists, sending feedback to the affected website may help. You can also send feedback to Apple by choosing Safari > Report Bugs to Apple.
