🐛 Troubleshooting

Common Issues

Agents not starting:

# Check Docker status
docker ps --filter "name=nexus-delta"

# View agent logs
docker-compose -f docker-compose-agents.yml logs quantflow-agent

API key errors:

# Verify environment variables
docker exec nexus-delta-quantflow-agent-1 env | grep ALPHA

# Check .env file
cat .env

Port conflicts:

# Check what's using ports 8080-8084
netstat -ano | findstr "808[0-4]"

Reset Everything

# Stop all services
./stop-simple.ps1

# Clean containers
docker-compose -f docker-compose-agents.yml down
docker-compose -f services/docker-compose.yml down

# Rebuild and restart
./start-simple.ps1
