Fresh install of CentOS 7 minimal & updated. Cloudmin 8.0. Created VM from CentOS 7.0 64-bit KVM instance with base OS. I cannot connect to the VNC via Flash, Java or TightVNC. Flash error: An security error occured (Error #2048). Check your policy-policy server configuration or disable security for this domain. Java error: access denied ("java.net.SocketPermission""host.server.com""resolve") TightVNC error: Error in TightVNC Veiwer: A connection attempt failed because the connected party did not properly respond after a period of time (set to 120 seconds), or established connection failed because connected host fas failed to respond. I tried changing webmin/config to referers_none=0 without success SSH works fine. No webmin installed on VM.
Unable to connect to graphical console

Make sure that port 843 is open on your system's firewall - this is needed for the flash object policy connection.

Thanks Jamie. I thought it was a firewall issue, but it looked as though iptables wasn't loaded and then I found the firewalld issue with webmin. I disabled firewalld and fired up iptables and then I was able to get everything working.
