port conflicts

Whether you're developing a new server application, setting up a local test environment, or configuring services on a Linux machine, encountering the “Address already in use” error can be a frustrating roadblock. This common issue indicates a port conflict, meaning that the port your application is trying to bind to is already occupied by another process. To resolve these conflicts and manage your applications efficiently, it's crucial to understand why these issues occur and how to address them. The error “Address already in use” typically appears when you try to start a server or service that binds to a specific TCP/UDP port, and that port is already occupied by another application.
