This error occurs when reading of communication with the license server failed due to timeout.
Possible causes include the following.
(1) Your PC security software is blocking or encrypting the communication.
(2) Your PC is communicating with the network via a proxy server (such as a network management server in a company or school).
For proxy communications, please read the following page.

(3) Your communication speed is extremely slow. (Authentication timeout occurs after 10 seconds.)
(4) There was congestion in communication at the license server. (Authentication timeout occurs after 10 seconds.)
When (3) or (4) is a possibility, either wait for a while and then try again, or follow the procedure below to configure the environment variables to extend the network timeout time for communication with the license server before trying again.
