no security type suitable for rfb 3.3 supported
Solution 1
I had to change the /etc/xrdp/xrdp.ini
i removed the conections xdrp2 -5 because these are not nessesary an i hard coded the username.
that did the trick for me
Solution 2
Try this:
$ vino-preferences
When your VNC client fails to connect with an error like “No matching security types” or “No security type suitable for RFB 3.3 supported” (or if you see a log line from vino-server like “Advertising security type 18") then type:
$ gsettings set org.gnome.Vino require-encryption false
Then try to connect again. Otherwise, post any pertinent logs.

I'm trying to set up an RDP connection from a W10 desktop to an Ubuntu 15.10 server. The connection is made but when I'm putting in my credentials to open the desktop on my server it's turning back to the start screen of the RDP session. To resolve this I tried the following solution.
Now I get an error:
started connecting connecting to 127.0.0.1:5900 tcp connected security level is 0 (1=none, 2=standard) error - problem connecting
This error occurs both on trying a local IP (within the LAN) and a WAN IP I'm totally new to Linux so please be a bit patient with me while I'll probably miss a straightforward solution.
I've found the following error in the logfiles:
rfbClientConnFailed("no security type suitable for rfb 3.3 supported")
