License server machine is down or not responding. (-96,491)

Summary

This article will explain how to overcome the (-96,491) error when using the Flexnet Publisher v11.13.1 toolkit.

Symptoms

When trying to connect to a license server with a client built with the Flexnet Publisher v11.13.1 toolkit, and there is latency between the two, then a "License server machine is down or not responding. (-96,491)" error may be thrown.

Cause

This is caused due the changes with the FLEXLM_TIMEOUT that where introduced in v11.13.1. The timeout default value for FLEXLM_TIMEOUT was set to 100,000 (0.1 second). This caused a -96,491 error when there was latency within a network.

Resolution

To increase the FLEXLM_TIMEOUT value to greater than 100,000 microseconds (0.1 second), for example 1500000 microseconds (1.5 second).
