Connect hangs forever

[drwtsn32x]

Sometimes the Connect() method will hang forever. I notice this happens when I reboot the SSH server. (My program that uses this library will automatically try to reconnect after a disconnection, and it's at this point when it hangs forever.)

Adjusting ConnectionInfo.Timeout has no effect on this problem.

Any ideas?

Same happens to me.
I updated from version 2016.1.0 to 2020.0.1 and with some machines Connection hang forever in new version whereas with old version connection was a successfull one.

This is the method I use for connecting:
@params.sshClient = new Renci.SshNet.SshClient(@params.connectionAsEvent.connection.Ip.Trim(), @params.GetPort() ?? 22, @params.GetUser(), @params.GetPassword()); @params.sshClient.Connect(); @params.shellStream = @params.sshClient.CreateShellStream("xterm", 80, 600, 0, 0, 32 * 1024);

And this is the exception it gave:
Error Renci.SshNet.Common.SshOperationTimeoutException: Session operation has timed out at Renci.SshNet.Session.WaitOnHandle(WaitHandle waitHandle, TimeSpan timeout) at Renci.SshNet.Session.Connect() at Renci.SshNet.BaseClient.CreateAndConnectSession() at Renci.SshNet.BaseClient.Connect()

It's done in #1274

This experiencing this issue with the latest version of the library (2023.0.1)
In my case it freezes on file open.

It happens once in 1-2 days. I'm connecting to the files served by this docker container https://github.com/atmoz/sftp on Azure VM
