RealVNC unable to connect to Ultravnc

Post by Thesus »

Hello,

So i setup Ultravnc since tightvnc security is very easy to hack. We were using RealVNC previously. UltraVNC has AD auth in, seems great.

Im able to login connecting using Ultravnc viewer but when i try RealVNC viewer to connect to ultraVNC server

Error:
Unable to connect to VNC Server using your chosen security setting.
Either upgrade VNC Server to a more recent version from RealVNC, or
select a weaker level of encryption.

I enabled the secureplugin ciphers and hit apply but still not able to use RealVNC viewer. Any ideas on how to fix this?

Thanks
