Zoho Mail SAML with Azure Active Directory

Zoho Mail SAML with Azure Active Directory

I've tried setting up SAML with Zoho Active Directory, and keep receiving an error message. I've tried setting it up both via the article posted by Zoho and by the article posted by Azure. I simply can't get it to work. PLEASE HELP!

Keep getting an error that says "Oops! Something went wrong. Try again later."

Both the error screenshot and certificate are attached.
