Mengatasi masalah tidak bisa remote console di vmware

Hari ini ada teman saya meminta tolong katanya server nya tidak bisa di remote desktop, kemudian saya coba remote console dari vsphere juga tidak bisa. Kebetulan ini server nya bisa untuk dilakukan restart, jadi saya coba restart vm nya dari vsphere.

Setelah vm nya kembali UP, ternyata masih sama tidak bisa juga di remote console, ada error nya “Unable to open MKS: Internal Error” when opening virtual machine console

Lalu saya mencoba mencari ke forum nya vmware, dan menemukan solusi nya :

Symptoms

After adding an ESXi host to vCenter Server 6.0 with running virtual machines, you experience these issues:
Opening a virtual machines console fails the vSphere Client and vSphere Web Client

Note:  Not all virtual machines experience this issue.

Opening a virtual machine console in the vSphere Client displays one of these error:

Unable to open MKS: Internal Error

Opening a virtual machine console in the vSphere Web Client displays one of these errors:
The console has been disconnected. Close this window and re-launch the console to reconnect.
Failed to initialize SSL session to remote host

In the /vmfs/volumes/virutal_machine_datastore/virtual_machine_folder/vmware.log file, you see entries similar to:

T| mks| W110: SSL: Unknown SSL Error
T| mks| I120: SSL Error: error:14094438:SSL routines:SSL3_READ_BYTES:tlsv1 alert internal error
T| mks| I120: SSL Error: error:140940E5:SSL routines:SSL3_READ_BYTES:ssl handshake failure
T| mks| I120: SOCKET 15 (143) recv error 0: Success
T| mks| W110: SOCKET 15 (143) Error during authd-VNC negotiation: (1) Asyncsocket error.


Purpose
This article provides options to resolve the Unable to open MKS: Internal Error error when opening virtual machine console.


Cause
This issue is caused by the SSL certificates are updated by the ESXi host when connecting to the new vCenter Server.  These certificates are used by the console and may not be updated with the virtual machine running.


Resolution
This is a known issue affecting ESXi 6.0.

To resolve this issue, use one of these options:
1. Power off and Power on the virtual machine.
2. Migrate the virtual machine to another ESXi host using vMotion.
3. Suspend and then Resume the virtual machine.

Note: The virtual machine must be powered off for the changes to take affect.  A warm reboot will not resolve the issue.

Kebetulan solusi nomor satu yaitu power off vm yang tidak bisa di remote console, dan di aktifkan kembali itu sudah cukup, jadi setelah vm nya UP, kami dapat melakukan remote console lagi.
