UNAUTHORIZED Error when connecting with make.com (Integromat)

UNAUTHORIZED Error when connecting with make.com (Integromat)

I'm getting this error when I'm trying to connect with the Zoho Desk Module in Make.com (Integromat). 

I have put the correct Orginisation ID from Zoho Desk > Settings> Developer Space > API > API Authentication. 

I am also using the correct Domain Extention (.eu). I have tried all the other domain extentions too.

Please help with this if someone can. Is it an authorisation error for my user account on Zoho? I only have one account and it's the owner.
