Zoho Mail SAML with Azure Active Directory

Zoho Mail SAML with Azure Active Directory

I'm trying to set up Zoho Mail with Azure Active Directory and I keep getting an error that just say Oops, try again later... I'm not sure why. I've tried pasting the PublicKey as well as importing it from the Base64 cert that Azure provides. I've followed directions from both Zoho support site as well as on the Azure website. I just simply can't get it to work. Please help!
