connect to ESXi over the internet issue: unable to connect to the mks: could not connect to pipe \\.\pipe\vmware-authdpipe within retry period

Good morning colleagues,

I’m trying to connect to my Esxi-6 over the internet. I am forwarding ports 443, 902, 903 to the Esxi server.

I can connect to the server but have an error on the VM’s console, namely:

unable to connect to the mks: could not connect to pipe \\.\pipe\vmware-authdpipe within retry period

Any suggestions?

Many thanks and good day,

Archie
