Re: Unkown connection error

vSphere Client is no longer available with the vSphere 6.5 release

Try The vSphere Web Client (Flash/Flex client)

The vSphere Web Client is supported on Chrome (latest and latest -1), Firefox (latest and latest -1), and IE10.0.19 and later (including IE11).

EXAMPLE:

https://YourESXIName.YourDomain.xxx/ui/#/login
