"The MX Records of your domain are not pointed to Zoho and you may not receive emails"

So I'm having a problem with our email accounts that says my MX records are not pointing to zoho.

"The MX Records of your domain(s) olem.com.ar are not pointed to Zoho and you may not receive emails in Zoho How to change MX records."

I looked in 000webhost and the MX records and it appears to be configured as it should be.

This happened all of a sudden, it was until today working fine!
