HTML Console SDK 2.1 fails to initialize

[thiyagarajan27]

I’m trying to connect to the VMs console using HTML Console SDK 2.1

It fails to initialize and the browser console log says “vnc authentication not implemented”

What configuration changes are needed in ESXi host get it working?

Interestingly it works on some ESXi hosts  and the browser console log says "security types/authentication scheme is 1". On the ESXi hosts where it fails, browser console log says "security types/authentication scheme is 2"

ESXi version where its NOT working: VMware ESXi, 6.0.0, 3073146

ESXi version where its working: VMware ESXi, 6.0.0, 2494585

--- browser console output where it’s not working on some ESXi hosts----

Hi there,

Firstly, can you confirm a couple of things for me on the non-working host.

1) Has this host been upgraded from a previous version of ESXi?

2) Can you post the contents of /etc/vmware/rhttpproxy/endpoints.conf

[thiyagarajan27]

1. Its not an upgrade.

2. Here is endpoints.conf contents

Thanks for supplying the info. I'm still investigating, it would also be useful if you could provide us the vmware.log file from a VM on the host where the console is not working, after you attempt to open a console.

You may have to enable logging in the VM's settings under VM options.

[elesueur · Accepted solution]

OK, the answer was staring me right in the face:

1. wmks.min.js:1 2016-11-03T05:24:54.101Z [Info ] Using authentication scheme: 2
2. wmks.min.js:1 2016-11-03T05:24:54.101Z [Info ] vnc authentication not implemented

The HTML console does not currently support VNC authentication. Do you have the following set in the VMX file?

RemoteDisplay.vnc.password

Actually, upon further testing, you can have that key set, but if you have

RemoteDisplay.vnc.enabled = "FALSE"

then you can still use the HTML console. So you just need to disable VNC for that VM.

Thanks Etienne!

We are also hitting the same issue  even after disabling the VNC. Please suggest.
