How to connect budibase (free cloudApp) to supabase[PostgreSQL] (free cloudApp)

[mad99]

Hi Community,
I'm new in the budibase universe.
Would like to tryout budibase with supabase.
But I can not connect the free cloudversion from budibase with the free cloudversion from supabase.
Tried every appraoch, search trough google, the docs and also GPT.

I always get an error:
Error creating datasource: Unable to connect - connect ENETUNREACH 2a05:d014:1c06:5f0b:4714:c587:a358:ce8b:5432 - Local (:::0)

GPT told me it could be a problem with IPv4 and IPv6.
But I can not find any solution or hint in the docs nore google.

Could someone push me in the right direction to find a working solution.
So I can tryout budibase cloud with supabase cloud.

Thank you
Martin
