It is always better to provide more precised details while posting a question. Explain what you are trying, where does this api call come from, what did you tried yourself to address the issue etc. We can not figure out the problem just with error log. 

Looking at the error message, your call to alfresco repository is timing out. Check if the repo is up and running.

[elonvengas]

Your Java socket is timing out means that it takes too long to get respond from other device and your request expires before getting response. This exception is occurring on following condition.

• Server is slow and default timeout is less, so just put timeout value according to you.
• Server is working fine but timeout value is for less time. so change the timeout value.

Solution: A developer can pre-set the timeout option for both client and server operations.

From Client side:

Socket socket = new Socket();
SocketAddress socketAddress = new InetSocketAddress(host, port);
socket.connect(socketAddress, 12000); //12000 are milli seconds

From Server side:

ServerSocket serverSocket = new new ServerSocket(port);
serverSocket.setSoTimeout(12000);
