Permission denied - I can't connect on my machine by OpenSSH

[harwadd]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

Do I need to have Windows Server OpenSSH already installed? Whenever it is installed it works normally, but when I don't have it installed it says "Permission denied", I tried all authentication methods.

Expected behavior

conta@0.tcp.sa.ngrok.io's password:
Sucefully! **connect**

Actual behavior

conta@0.tcp.sa.ngrok.io's password:
Permission denied, please try again.
conta@0.tcp.sa.ngrok.io's password:

Yes, the machine that you are connecting to needs to have SSHD installed. Based on the debug output, it looks like it is already installed. Can you provide more info on what OSes you are connecting from and to? If possible, can you provide the server logs?
