Network resource exhaustion typically manifests as slow connectivity, timeouts, or dropped packets, not a specific application-level message about too many concurrent sessions.

If the software were out of licenses, the error message would typically be license-specific, such as 'License limit reached' or 'Licensing error,' rather than indicating an issue with concurrent sessions from a resource perspective.

The error message 'too many concurrent sessions' directly points to the system's inability to handle the active user load. Even with recommended specifications, a 'small VM' might not possess sufficient processing power (CPU and RAM) to efficiently manage a high number of simultaneous user requests and maintain their session states, leading the application or underlying OS to deny new connections to prevent further resource exhaustion.

A misconfigured firewall would generally block connections outright or prevent access to specific ports, not allow connections to reach the application and then report 'too many concurrent sessions.'
