Ever wondered why an application works perfectly on your machine but fails in production?
It could be environment variables, network configuration, permissions, or a service listening on the wrong interface.
For example, an app bound to 127.0.0.1 may work locally but remain inaccessible from other machines or containers.
Debugging isn't just about fixing code. It's about understanding the environment in which that code runs.
What's the most frustrating “works on my machine” bug you've encountered? 😅
