Yodel.io will not connect with Make

Hello,
We have some automations involving Yodel.io already with Zapier however we are getting some errors involving international numbers that I think we can handle better with Make. However when we go to connect Make to Yodel from Yodel.io we are getting a weird message that will not allow us to get a token to integrate the platform.

Any info on why this is and if there is anything we can do to fix this?
Thank You
