Trello - Zoho Power-up error while authenticating

Trello - Zoho Power-up error while authenticating

Hi, I am trying to add the Zoho Power-Up to my Trello board. But I get an error while authenticating telling me ERROR invalid_client. I think it is because it is trying to authenticate with Zoho.com while my zoho account is on the Zoho.eu server.

Can you help me?

Regards,
Nicola
