Professional Fix Guide: Hugging Face Deployment Database Issue

Issue Summary

Your Hugging Face Space is failing with a network connectivity error: [Errno 101] Network is unreachable

Root Cause Analysis

The error indicates that the Hugging Face container cannot reach your Supabase database. This is typically caused by:

Supabase project being paused or suspended
Incorrect database credentials
IP restrictions on the Supabase project
Regional connectivity issues

Professional Solution Steps

Step 1: Verify Supabase Project Status

Access Supabase Dashboard: https://supabase.com/dashboard
Locate your project and verify:
- Project status is "Active" (not paused)
- Project is not suspended
- Project is in a supported region

Step 2: Obtain Correct Connection String

In your Supabase project → Settings → Database
Copy the connection string from the "Connection string" section
Verify the format: postgresql://postgres:[password]@[host]:5432/postgres

Step 3: Update Hugging Face Space Secrets

Navigate to your Space: https://huggingface.co/spaces/danishjameel003/assitantchatbot
Go to Settings → Repository secrets
Update or add these environment variables:

SUPABASE_DB_URL=postgresql+asyncpg://postgres:[YOUR_ACTUAL_PASSWORD]@[YOUR_ACTUAL_HOST]:5432/postgres
ENVIRONMENT=production
OPENAI_API_KEY=your_openai_api_key_here
SECRET_KEY=your_secret_key_here
DEBUG=false
HOST=0.0.0.0
PORT=7860

Critical: Replace [YOUR_ACTUAL_PASSWORD] and [YOUR_ACTUAL_HOST] with your real values.

Step 4: Test Connection Locally

Run the connection test script to verify your credentials:

python simple_connection_test.py

Step 5: Redeploy Your Space

After updating secrets, return to your Space
Trigger a redeploy or wait for automatic redeployment
Monitor the logs for successful connection

Alternative Solutions

Option A: Create New Supabase Project

If the current project has issues:

Create a new Supabase project in a different region (e.g., US East)
Use the new connection string in your Space secrets
Redeploy your Space

Option B: Check IP Restrictions

In your Supabase project → Settings → Database
Review any IP restrictions
Remove restrictions temporarily or add Hugging Face IP ranges

Option C: Alternative Connection Format

Try this format in your Space secrets:

SUPABASE_DB_URL=postgresql://postgres:[PASSWORD]@[HOST]:5432/postgres?sslmode=require

Verification Checklist

After implementing the fix, verify:

Supabase project is active and accessible
Connection string is correctly formatted
All environment variables are set in Space secrets
Space has been successfully redeployed
Logs show successful database connection
Health endpoint responds correctly: https://danishjameel003-assitantchatbot.hf.space/health
