Q: cannot open Netflix. to many redirects

I have an iMac  using Safari version 9.01.  Can't open Netflix.  Message says to many redirects.  I recently connected a new modem to Comcast Xfinity.  No problem opening other web pages.  No problem opening Netflix on my IPad of TV.  I am not that tech savvy so solving this problem may be simple.  Any advice would be appreciated.
