CNAME / TXT Method Validations Failed

CNAME / TXT Method Validations Failed

Hi,
I just purchased the Zoho solution for email and I'd like to setup everything for my Shopify store.
Unfortunately I encounter some troubles with the domain verification.
I tried both CNAME Method and the TXT Method but neither work.

I always get the same type of popup (

Help would be much appreciated.
Thanks for the support.
Thomas
