Unable to connect directly to Esx via the vSphere Client.

[alteirac]

Hello,

I can not connect directly to Esx via the vSphere Client. I have the next message :

   "Can not log in to the vSphere Client "xxx". An unknown connection error occurred. (

The client could not send a complete application to the server. (The underlying connection was closed. An unexpected error occurred when sending.))."

The esx respond to ping and name resolution are correct. They are seen by the vCenter and sshh connection to esx is possible.

Version : Esxi, 5.5.0, 1892794

VSphere Client 5.5.0, 1880841 on Windows XP SP3

Thank you for your help

Hi,

Please check your firewall and make sure about openning port 443 and 902 both TCP and UDP.

Hi,

Thanks but I do not have a firewall between the vSphere Client and the Esx. They are on the same subnet.

The firewall on the machine, where the vSphere Client is installed, is disabled.

Port 443 and 902 are opened on the Esx
