I have got the same error message as in discussion 2007405:
:smileycry: "Unable to connect to the MKS: The remote host certificate has these problems:" ![]()
The "problems" are not specified. The above mentioned solution to create new certificates does not help. At least not without rebooting the host.
Additionally as I am not using a vCenter Server I can not "remove the Host an re add it"
Until yesterday everything works fine. There was not reboot neither on the host nor on the running clients.
The message is the same for all running clients. The clients seem to be healthy as far as I can contact them via ssh.
What to do? ... just reboot the host?

Still no solution:
BUT: Still impossible to connect to client consoles :smileyangry:

Hi
actually I am in the same situation now.
I have changed nothing at all and I get this error: "Unable to connect to the MKS: The remote host certificate has these problems:"
Additionaly I see this error:
W110: SSL: Unknown SSL Error
2013-07-22T14:33:34Z vmauthd[10348866]: vthread-3| I120: SSL Error: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
2013-07-22T14:33:34Z vmauthd[10348866]: vthread-3| W110: VMAuthdSocketRead: read failed. Closing socket for reading.
What could be wrong?
I use only vSphere Client with no vCenter.
Any clues?
I've got the same problem since last week. Changing the cetrificate doesn't solve the problem.
Is there a solution known?
Thanks!
Does any body have an update??
Was anyone actually able to solve this?
This is mighty annoying, and VMWare has not piped up about this at all...
I attempted to use this VMWare KB Article, which had no effect:
I had this issue on 2 different servers.
I was able to work around this in one of the servers by enabling the Virtual Console over VNC.
These 2 references proved very useful. I hope this helps anyone else out there:

Are you able to telnet to ESX host on port 902 ?
MKS=Mouse Keyboard Screen, these components activities are rendered over the network through port 902 from host to client machine.
Certificate error may be misleading, if it is indeed a certificate error or corruption, you can simply ssh to the ESX host as root and run sh /sbin/generate-certificates.sh. This should fix it.
Hi , Even i faced same problem today.
While installing OS on new VM the error was flashing "Unable to connect to the MKS: The remote host certificate has these problems"
I follow below steps to resolve this issue.
1. Restart host.
2. Disconnect and reconnect host from vcenter.
I suspect the problem is with host certificate.
Did you try below KB article?
Is it showing in all host or any specific host?
if not in all host then did you try migrating VM to other working host? Did this resolve the issue?
If other host doesn't have same issue in cluster/VC, then i would suggest to remove particular ESXi host from VC and readd it back

Hi,
In our case reboot the host, remove the host from vCenter, and then re-add the host back fixed the issue.
