# Troubleshooting Guide

## Common Issues

### Missing Dependencies
Ensure all dependencies are installed:
```bash
pip install -r requirements.txt
```

### Deployment Failures
#### Docker
Check container logs for errors:
```bash
docker logs <container_id>
```

#### Kubernetes
Inspect pod logs for failures:
```bash
kubectl logs <pod_name>
```

### Network Issues
#### Check Network Connectivity
Ensure that your system has a stable internet connection. You can check the connectivity by pinging a reliable server:
```bash
ping google.com
```

#### Firewall and Proxy Settings
Ensure that your firewall or proxy settings are not blocking the necessary connections. You may need to adjust the settings or whitelist certain IP addresses and ports.

### Configuration Errors
#### Environment Variables
Ensure that all required environment variables are set correctly. You can list all environment variables using the following command:
```bash
printenv
```

#### Configuration Files
Check the configuration files for any errors or missing values. Ensure that all required fields are filled in correctly.

### Application Errors
#### Check Application Logs
Inspect the application logs for any error messages or warnings. The logs can provide valuable information about what went wrong and how to fix it.

#### Restart the Application
Sometimes, simply restarting the application can resolve the issue. Use the appropriate command to restart the application, depending on how it was deployed.

### Database Issues
#### Check Database Connection
Ensure that the application can connect to the database. You can test the connection using a database client or command-line tool.

#### Database Migrations
Ensure that all necessary database migrations have been applied. You can check the migration status and apply any pending migrations using the appropriate command for your database system.
