How do I resolve an "Error code 10009: Token expired"?

When a machine/container is creating a Gurobi environment, a token is retrieved from our WLS license server and stored on disk. Subsequent Gurobi processes that require a token will first check the existence of a valid token. If the token has expired or is not available, the warning message "token expired" will appear in the client logs, and a new token is requested. It's worth noting that the life of a WLS token can be adjusted with the WLSTokenDuration parameter.  

One cause that may prompt this error for no apparent reason is that the internal clock of the machine or container running Gurobi is out of sync with our license server. Our license server references a Network Time Protocol (NTP) such as pool.ntp.org. We allow for a time drift of two minutes but anything beyond that is considered out-of-sync. To prevent this from happening, please ensure your system clock is synchronized correctly with a NTP server.
