VMware “Unable to connect to the MKS:”

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

  • Open /etc/vmware/config with a text editor.
  • Add this:  vmauthd.server.alwaysProxy = “TRUE”

Check your firewall config/network setup.    This error is caused by your vSphere client not able to communicate with the ESX/ESXi host directly.

All “Unable to connect to the MKS:” errors are network issues.   Do not be fooled by the mention of certificate issues…
