Hello,

Yes, we did not do anything wrong. We just tried to deactivate your third party plugins for testing purposes and then it displays the “page not found ERR_TOO_MANY_REDIRECTS“ and it did not let us access your admin area.

It seems some of your third party plugin is the cause of this issue. You can check the below article for this purpose:

Your site is working just fine just the admin area is not accessible. You can check the below screenshot:
