Hello VMware Community,
I'm encountering an issue when trying to connect to an HTML console via WebSocket. Below is the process I followed and the error I'm experiencing. Any guidance would be greatly appreciated.
Using Python, I retrieved VNC connection information for a virtual machine. The code snippet used is as follows:
Using Python, I retrieved VNC connection information for a virtual machine. The code snippet used is as follows:
try:
ticket = vm.AcquireMksTicket()
print("VNC connection information for {}:".format(vm_name))
print("Host: {}".format(ticket.host))
print("Port: {}".format(ticket.port))
print("Ticket: {}".format(ticket.ticket))
print("SSL thumbprint: {}".format(ticket.sslThumbprint))
except vmodl.MethodFault as e:
print("Failed to get VNC connection information: {}".format(e.msg))
exit(1)
This resulted in the following
VNC connection information for dev-test - 10.xxxxxxxxxxxx:
Host: ch1-dev-esxi1.lab.local
Port: 902
Ticket: 52xxxxxxxxxxxxxxxxxxxxxxxx
SSL thumbprint: [Thumbprint]

However, when attempting to use this information to connect to the HTML console, I'm facing a WebSocket connection failure. The error message is:
WebSocket connection to 'wss://[IP]:[Port]/ticket/[Ticket-ID]' failed
Here's the HTML and JavaScript code I used for the connection:
<!DOCTYPE html>
... [Rest of the HTML code] ...
<script>
var wmks = WMKS.createWMKS("wmksContainer",{})
.register(WMKS.CONST.Events.CONNECTION_STATE_CHANGE, function(event, data){
if(data.state == WMKS.CONST.ConnectionState.CONNECTED){
console.log("connection state change: connected");
}
});
wmks.connect("wss://ch1-dev-esxi1.lab.local:902/ticket/52dxxxxxxxxxxxxxxx");
</script>
</body>
</html>
Additional Checks:
- The VM is running without issues.
- VMware Tools are installed, current, and running (Version 12288, 12.0.0).
I'm unsure why this WebSocket connection is failing. Has anyone experienced a similar issue or can provide some insights into what might be going wrong?
Thank you in advance for your help!
