People who use Bitvise SSH Client in Windows 10 may experience an error when attempting to connect to their Nectar VMs:
The SSH2 session has terminated with error. Reason: Error in component session/transport/kexHandler. Error class: Flow, code: ComponentException, message: Exception in component: Windows CNG (x86) with additions: AsymKey: CngAgree: unexpected secretData->cbStruct.
This can be solved by upgrading Bitvise (solution via https://stackoverflow.com/questions/50255174/bitvise-ssh-error-after-windows-10-1803-update)
