Hi, Looks like you either did not set the discovery section correctly, there is a network issue preventing the C# thin client from connecting, or the server itself has not started or is not responding.
message: because connected host has failed to respond. 171.159.66.12:10800 Make sure that the clientconnector is up and running at port 10800: see: https://ignite.apache.org/docs/latest/thin-clients/getting-started-with-thin-clients#configuring-thin-client-connector Make sure that the Server has started and that you are able to connect to it via other thin clients. Try using sqlline: https://ignite.apache.org/docs/latest/tools/sqlline There is also the possibility that the default timeout is not enough for your use case: https://ignite.apache.org/releases/2.9.0/javadoc/org/apache/ignite/configuration/ClientConnectorConfiguration.html#setHandshakeTimeout-long- see this example for a simple C# client: https://github.com/apache/ignite/blob/master/modules/platforms/dotnet/examples/Apache.Ignite.Examples/ThinClient/ThinClientPutGetExample.cs doc: https://ignite.apache.org/docs/latest/thin-clients/dotnet-thin-client Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
