I have cleared cache, cookies and what not everything. Still getting below error.
The webpage at https://scn.sap.com/saml/sso might be temporarily down or it may be have moved permanently to a new web address.
Error code : ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Do I need to uninstall and install it again? 
Updated:
When I connect from home its working, but when I connect from office I'm getting above error. IE is working fine in both home and office.
