Trying to connect Zoho Recruit via Oauth

Hey everyone! So recently I have been trying to connect Zoho Recruit with Bubble.io via API. They are using Oauth 2.0 as their authorization framework and they have step-by-step documentation that I used to configure the API connection. After following the steps and passing the data, I still encounter the following issue:

It says "There was an issue setting up your call.
Temporary error connecting to this service (raw message:

"

Please help me with this integration. I would highly appreciate it!
