You appear to be trying to use a SOCKS proxy that is not running or reachable.

Caused by: java.net.SocketException: Can't connect to SOCKS proxy:No route to host: connect

Make sure that the proxy is actually running, and that it can reach the PostgreSQL server. Try using psql to connect to the PostgreSQL server via your SOCKS proxy to verify that works - assuming you intended to connect via the proxy.

Have you set the socksProxyHost and socksProxyPort system properties, perhaps via the java command line? See this Java documentation on proxies.

Are you specifying a proxy to your JDBC connection?
