This error occurs either when the destination host is down or when problems in the network cause a loss in transmission.
Repair or reboot as necessary.
If the above does not solve the problem, check the network cabling and connections.
No connection was established in a specified time. A connect or send request failed because the destination host did not properly respond after a reasonable interval. (The time-out period is dependent on the communication protocol.)
The symbolic name for this error is ETIMEDOUT, errno=145.
