TrileadSSH2Java_213 clients and VNC clients to TigthVNC server with SSH2 tunel crashes when authentication is correct

[md500]

Prerequisites

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

Steps to reproduce

I am trying to connect via SSH tunnel to the TigthVNC server.

I thought I was going to connect correctly as I would connect from Bitvise SSH Server and have the VNC client connect me correctly through the SSH tunnel and ask for the VNC password as in this image:

But, in this case, when doing the SSH tunnel with OpenSSH_for_Windows_9.5p1, LibreSSL 3.8.2 (Beta) with the same credentials, the client closes and shows me the following (error) message and does not connect:

Expected behavior

I tried with Bitvise SSH server, and it connects correctly with these steps:

* C:\Users\mau> ssh -v -L 5901:localhost:5900 -C -N -l mau 100.99.55.88
* Login to TigthVNC server using "localhost:5901" from TigthVNC Client (TigthVNC server settings must have "allow Loopback connections" and "Require VNC password" enabled)

* Input VNC Password
* Vnc client shows correctly

Actual behavior

With OpenSSH_for_Windows_9.5p1, LibreSSL 3.8.2 (Beta)

* C:\Users\mau> ssh -v -L 5901:localhost:5900 -C -N -l mau 100.99.55.88
* Login to TigthVNC server using "localhost:5901" from TigthVNC Client (TigthVNC server settings must have "allow Loopback connections" and "Require VNC password" enabled)

* Message Error: Connection has gracefully closed (and it doesnt connect without asking VNC password...)

Options on sshd_config changed to show in a log:
