I've been trying to Google, but all of the issues refers connection from PC to remote VNC server.
So. I have an issue with VNC communication from Android to Linux. I have installed a TightVNC Server on latest Ubuntu version which works fine if I connect to it from PC with RealVNC Viewer on port 5901.
I downloaded a VNC Viewer by RealVNC for Android and if I try to connect to my remote host it says "Too many authentication failures" even on first try.
I also tried a couple different VNC Viewers, but result is exactly same.
What would be the reason and how I am able to fix it? Some people were speaking about that the client can be unsecure, but I'm not sure what difference there would be with PC and Android version of VNC.
From PC to remote: Works
From Android to remote: Doesn't work
About half-year ago on my different server I had no similar issues. It was working fine, no matter what device I used to connect VNC if I knew IP, port and password.
