Avalanche/RealVNC Server

Unable to get Avalanche (V 0.28) to talk to RealVNC Server (V 6.8.0) on Windows 10. Has anyone got this combination to work please?

@ Richard

I normally use it the other way around, however few things come to mind:

1) Have you disabled encryption on the RealVNC Server?
2) Have you checked that the VNC Server port is what Avalanche expect?
3) Have you checked that Protocol version is not set above 3.8?
4) Using VNC Password instead of user authentication (I do not remember if Avalanche supports User Authentication, aka user name and pwd, sorry)

More info on the RealVNC Server parameter lists here: https://help.realvnc.com/hc/en-us/articles/360002251297-VNC-Server-Parameter-Reference-

Avalacnhe, AFAIK, handles VNC Protocol 3.3, 3.7 and 3.8. I am not aware if later protocols support has been added, sorry.

Hope this helps!

Thanks for your reply Paolo. Ref your questions – following changes made:

1. Set for ‘Always off’
2. Believe default of 5900 should be OK
3. Protocol version set for 3.8
4. VNC Password set for Password Authentication only

The link to RealVNC Server parameter list was very useful even if I couldn’t get it to work – what a long and complicated list!

No matter although not so secure I’ve downloaded TightVNC and it worked first time.

what a long and complicated list!

Indeed!

On my setup Avalanche stopped listening to RealVNC months ago. I’ve tried numerous things (mostly without knowing what I was doing), to no avail.

This weekend I decided to install the TightVNC server on the Windows side: same problem. But then per accident, I had a look at Avalanche’s title bar and saw that it was using port 5901, rather than port 5900. And only then, after some blind tries, I suddenly realised that the mysterious ‘Screen’ button was responsible for that. Setting it to 0 brought back the long missed connection.

I haven’t re-installed the RealVNC server, but I suppose that it would work as well, since it has done so for many years.
The only question remaining is: how did I manage to change that Screen to 1?

That always catches people out, a VNC server can support 10 or more screens on the 59xx ports, the problem is some start at 0 and others at 1 (although I have seen one which 5910 is the default).
