Settings VNC_PASSWORDLESS to 'true' results in 'ERR_CONNECTION_REFUSED'

[GOvEy1nw]

Hi, this is a great container, thank you.

I've set it up on my Unraid server, and I wanted to use it without a password as I'm only accessing locally. However when I add 'VNC_PASSWORDLESS' with the value 'true' as a variable, it no longer works and results in 'ERR_CONNECTION_REFUSED' .

If I set it to 'false', it works fine. If I set VNC_PW to be blank, and keep 'VNC_PASSWORDLESS' set to false, it also works fine (though still have to click the popup). If I set VNC_PW to be blank, and set 'VNC_PASSWORDLESS' to true, it no longer works and results in 'ERR_CONNECTION_REFUSED' .

There's no errors in the docker log. The noVNC heading says 'Something went wrong, connection is closed'.

Is there a fix for this please?

Hey guys,

I've looked at the VNC base image documentation to try finding if there are issues with VNC_PASSWORDLESS. However, I haven't found any. The developer is just suggesting to use this variable. When you set this variable to VNC_PASSWORDLESS equal true, how did you set it? Did you set the value as a boolean or string?

I am going to try testing it this weekend in my home lab and get back to you.

Unfortunately, this variable is set by the VNC base image not me.

Another way to access the container without clicking the pop-up I use this URL: http://localhost:6901/?password=vncpassword. Replace localhost with your machine host IP. Of course in this instance I am using the default password from VNC.

This sucks that you cannot save the password on your vnc client. Have you tried using RealVNC client? If I remember correctly, you can save your password. What OS do you use?

windows for the front end.

i used to use realVNC some years ago, but ran into issues that tightVNC solved. for the life of me i dont remember what those issues were. it may have been related to using it on a windows server (which i dont have any more). i'll give realVNC another try.

thanks for the tip. steve.

It appears there's a bug on their side. When I use the debian version container and set the variable, the container doesn't start. If I use the Rocky base version and set the variable the container is starting well. I am going to open a case with them and see if there's anything to do to fix this.

Updates from my issue raised:

It seems this was fixed in the most recent commit https://github.com/ConSol/docker-headless-vnc-container/commit/94657f6ae0a1b58fb451dfa6e48b61729b0a488f.
The corresponding image is available on Docker Hub using the nightly tag.

Once is in the stable channel I will rebuild the image and push a new update.
