> Currently, the thin client waits indefinitely for SSL handshake completion
> without any timeout (see
> org.apache.ignite.internal.client.thin.io.gridnioserver.GridNioClientConnectionMultiplexer#open).
> If the remote endpoint stops responding during the SSL handshake but does not
> close the socket, the thin client hangs indefinitely with the following stack
> trace:

> This situation may occur when thin client traffic is proxied by a container
> or pod, for example:
> {code:java}
> thin client -> inbound socket | poxy | outbound сокет -> server
> {code}
> If only the `outbound socket -> server` closed while the proxy keeps the
> inbound socket open, the client never receives a socket close event and
> continues waiting indefinitely for the SSL handshake to complete.
