Vmware console over the internet

we have esxi 6.7 hypervisors. i can enable vnc on them, but the manageiq says it’s not supported after 6.5. so that’s a dead end. so

the webbased isn’t working also, the message is “the web based console is not available because the windows platform does not support it”

what does it mean? what can i do with it? i can have the vmrc working, but only when i use something like a vpn that can directly communicate with the vcenter, i need something that can work over wan.

thank you
