[Action Required: Windows XP OS users] End of Support for 3DES Cipher
For security reasons, we have discontinued the support for 3DES Cipher. After this discontinuation of support for 3DES cipher, machines running on Windows XP, that do not support any more recent and secure ciphers than 3DES, will not be able to access the Sign In and My Account pages.
If you're a Windows XP user, we strongly recommend upgrading your OS.
