Hi!

When connecting to the sftp server, the method SftpClient.ConnectAsync hangs(timeout not working).

My configuration:
Timeout: 60s
OperationTimeout: 10s

OS: windows server 2019
SSH.NET version: 2024.0.0
NET version: 8.0

Stack trace:

System.OperationCanceledException: The operation was canceled. at System.Threading.CancellationToken.ThrowOperationCanceledException() at System.Threading.CancellationToken.ThrowIfCancellationRequested() at System.Net.Sockets.Socket.AwaitableSocketAsyncEventArgs.ThrowException(SocketError error, CancellationToken cancellationToken) at System.Net.Sockets.Socket.AwaitableSocketAsyncEventArgs.System.Threading.Tasks.Sources.IValueTaskSource<System.Int32>.GetResult(Int16 token) at Renci.SshNet.Connection.ProtocolVersionExchange.SocketReadLineAsync(Socket socket, List1 buffer, CancellationToken cancellationToken) at Renci.SshNet.Connection.ProtocolVersionExchange.StartAsync(String clientVersion, Socket socket, CancellationToken cancellationToken) at Renci.SshNet.Session.ConnectAsync(CancellationToken cancellationToken) at Renci.SshNet.BaseClient.CreateAndConnectSessionAsync(CancellationToken cancellationToken) at Renci.SshNet.BaseClient.ConnectAsync(CancellationToken cancellationToken)

Thank you in advance!
