SilverPAY Server Fix Instructions

Issue Summary

SilverPAY on Hostinger server (31.97.57.205:8001) is returning HTTP 500 errors when attempting to create payment orders. The health check returns 200 OK, but the /api/v1/orders endpoint fails.

Root Cause

The SilverPAY container is missing critical configuration:

1. Database initialization (SQLite schema)
2. HD Wallet mnemonic seed
3. Exchange rate API configuration
4. Environment variables

Temporary Solution (Active)

We've enabled a mock payment service locally:

• Set "UseMockService": true in appsettings.json
• This allows full testing of the payment flow
• Mock service simulates payment confirmations after 5 seconds
• Remember to set to false before production deployment!

Permanent Fix - Server Commands

SSH into the server and run these commands:

# 1. Find the SilverPAY container
docker ps -a | grep silverpay

# 2. Check container logs for specific errors
docker logs [CONTAINER_ID] 2>&1 | tail -100

# 3. Navigate to SilverPAY directory
cd /root/silverpay  # or /opt/silverpay

# 4. Create .env file if missing
cat > .env << 'EOF'

# 6. Restart the container
docker-compose down
docker-compose up -d

# 7. Test the fix
curl -X POST http://localhost:8001/api/v1/orders \
  -H "Content-Type: application/json" \
  -H "X-API-Key: sp_live_key_2025_production" \
  -d '{
    "external_id": "test-order",
    "fiat_amount": 10.00,
    "fiat_currency": "GBP",
    "currency": "BTC",
    "webhook_url": "http://localhost:8080/webhook",
    "expires_in_hours": 24
  }'

Alternative: Docker Run Command

If docker-compose isn't available:

docker run -d \
  --name silverpay \
  --restart unless-stopped \
  -p 8001:8001 \
  -v $(pwd)/data:/app/data \
  -v $(pwd)/.env:/app/.env \
  -e PYTHONUNBUFFERED=1 \
  silverpay:latest

Verification Steps

1. Check health: curl http://31.97.57.205:8001/health
2. Check API docs: curl http://31.97.57.205:8001/docs
3. Test order creation with the curl command above

Important Notes

• The WALLET_MNEMONIC shown is for testing only - generate a new one for production
• Consider setting up proper blockchain API keys (BlockCypher, Blocknomics)
• Monitor disk space for the SQLite database
• Set up proper logging and monitoring

Rollback Instructions

If issues persist:

1. Set "UseMockService": false in appsettings.json
2. Restore original SilverPAY configuration
3. Contact system administrator for server access
