Communications timeout. License Manager Error -139.
How can I start MATLAB?

This error may occur if your FLEXnet server is configured with an options file that uses HOST_GROUP's with wildcards. For example:
HOST_GROUP labs 192.168.*.*
INCLUDE MATLAB labs
To workaround this issue, configure the HOST_GROUP with exact IP addresses. For example:
HOST_GROUP labs 192.168.1.1 192.168.1.2 ...
Contact your license administrator to resolve this issue, as the options file resides on the license server.
