Vmware-vmrc.exe isn't compatable with SSL over port 902. To resolve this issue use one of the following solutions.
1. vSphere
Go to ESXi configuration Menu -> Advanced Settings -> Config-> Defaults -> security-> host Uncheck "Config.Defaults.security.host.ruissl"
2. From a linux system with vSphereCLI run:
vicfg-advcfg --server servername -s false Config.Defaults.security.host.ruissl
3. On the ESXi 5.1 Hypervisor* run:
vim-cmd hostsvc/advopt/update Config.Defaults.security.host.ruissl bool false
*Note to perfrom step 3 you'll need to have enabled the ESXi Shell from the ESXi console screen, <F2> Customize System, option "Troubleshooting Options", and then hit Alt+F1 to open a local shell. Alternatively you can also enable SSH from the console screen as well and then SSH to ESXi.
