Issue/Introduction
Unable to connect with Studio, getting "java.net.SocketException: Unexpected end of file from server"
Resolution
The error is a socket exception, and it typically means one of the following:
1. The TDV server is not running.
2. The Postgres repository is not running.
3. There is a network problem.
Verify that the TDV server and the Postgres repository are running. On Windows, you can do so by bringing up Windows Services and checking whether the two services are started. On Linux, you can use the following commands:
ps -elf | grep ServerBoot
ps -elf | grep postgres
Once you have verified that both processes are running, find out whether you can connect to TDV using the Web Manager (i.e. using your browser). If you are able to connect successfully using a browser, it means that TDV is running (and is responding), and so the issue lies with Studio or your network. Restart Studio. If this does not help, it indicates that there is a network problem or a firewall issue in your environment which is preventing Studio from connecting to TDV.
