Hi,


I've seen issues relating to the KVM before, although I don't remember this one specifically.


Have you restarted the management agents on the host?
Have you tried another administrator login to vSphere/Host to test the credential issue?

This Seems your backend storage is not connected to the esxi where you kept your VM(VMDK files).

Can you login in ESXi and check the vmdk file size if its shows 0 then please do check your back end connected storage device.

If you find any answer useful. please mark the answer as correct or helpful.

I had this same problem.  My vSphere server (dual nics) on different networks (which were not routing) was the issue.

Could you give me more details about the situation? I seem to have the same problem. vCenter has 2 NICs, one NIC is connected to clients' network from which I access it; the other NIC is used to connect and manage ESXi host. I can open VM console if I login host from vSphere client, but when I login vCenter from vSphere client, I cannot open VM console, just see the error:

Unable to connect to the MKS: Login (username/password) incorrect.

Look forward to your help, thanks in advance!

I had this issue today, and it turned out to be that I had inadvertently erased the host's default gateway.

vSphere into the host, click on the configuration tab, and open DNS and Routing.

Click Properties, and open the Routing tab. Ensure your correct default gateway is set. Mine was blank.

Setting the default gateway here corrected "unable to connect to the MKS: login (username/password) incorrect" issue for me. Hope this helps someone else as well.
