Direct Database Connection Refusing Port 5432 After Working Yesterday

What I'm trying to achieve:
Connect to my Supabase database using direct database access (my account has the ipv4 add-on) through a Docker container running Letta/MemGPT.

What's going wrong:
Connection was working perfectly yesterday, but today getting "Connection refused" on port 5432. The database host IP appears to be completely unreachable.

Environment details:
  • OS: Ubuntu 24.04 (WSL2)
  • Platform: Docker container
  • Database driver: pg8000 (PostgreSQL)
  • Project ID: pvxhhmwxdcsvlqouptuc
  • Database host: db.pvxhhmwxdcsvlqouptuc.supabase.co (resolves to 15.157.30.159)
Error:
pg8000.exceptions.InterfaceError: Can't create a connection to host db.pvxhhmwxdcsvlqouptuc.supabase.co and port 5432


Troubleshooting completed:
  • Verified no configuration changes on my end
  • Confirmed direct database access is enabled in dashboard
  • Checked Supabase status page (no outages)
  • Network tests show 100% packet loss to the IP address
  • DNS resolution works correctly
Connection string format:
postgresql://postgres:PASSWORD@db.pvxhhmwxdcsvlqouptuc.supabase.co:5432/postgres

Could this be related to infrastructure changes on the Supabase side? The IP seems completely unreachable from multiple network tests.

Any guidance would be appreciated!
