I'm experiencing persistent OAuth errors when trying to connect Make with Zoho API. I've tried multiple approaches but keep encountering the following issues:

1. First error: 'Invalid Redirect Uri - Redirect URI passed does not match with the one configured' when attempting to authenticate from Make to Zoho.
2. Second error: When the OAuth flow redirects, I get '{"message":"Not found"}' at the URL 'https://eu2.make.com/oauth/wait'

I've already:

• Added multiple redirect URIs in my Zoho API client settings including:
  • https://eu2.make.com/oauth/cb/zoho
  • https://www.make.com/oauth/cb/zoho
  • https://eu2.make.com/oauth/callback/zoho
• Set the Homepage URL to https://eu2.make.com in my Zoho client settings
• Tried creating new connections in Make
• Verified my client ID and secret are correct

Could you please advise on the exact redirect URI configuration needed for Zoho integration with EU2 region accounts? Is there a known issue with the OAuth wait endpoint? Any specific troubleshooting steps you'd recommend for resolving these errors?
