can't connect my vsphere client to manage my host...pls help!!

[BITP]

Thank you for reading...i am new to esxi 5.1 and  inherit a Dell T110 running one -250gb HD for OS (Esxi and Server 2008 r2) and 2-1TB H.D for SHARE DATA mirrow with Microsoft software......(what a mess ah)

everything was going well till about 2 weeks that i can't connect to mange the server,  it's giving me the error:

Vsphere client could not connect to "IP"

AN unknown connection error occurred. ( The client could not send a complete request to the server. (The underlying connection was closed: An unexpected error ocurred on a send.))

If i point the browswer to the host IP as: https://hostip (page cannot be display)

-Windows server is up and running

-i can ping the Esxi

Problem is that i  have to upgrade the memory,  and i am affraid that after that  i won't connect.....and then i am in big trouble...because i have to manually turn on the server inside the Esxi.

I do have backup, but the person before me was not doing backups with veeam..instead they used regular windows backup software to a usb drive....i tried to create a baremetal recovery and of course did not work...it was asking me for a driver....i believe it was for the hard drive....i have free veeam now..but i can't connect it either...to the Esxi box.

i would appreciate any suggestion.....thanks in advanced.

Do you have physical console access to the Dell T110?  Can you log in there?  If so, you could restart the management agents:

VMware KB: Restarting the Management agents on an ESXi or ESX host

You could also enable the shell which would allow you to try all sorts of connectivity tests:

VMware KB: Using ESXi Shell in ESXi 5.x

Connectivity tests:

Hey BITP,

1 quick possibilty...duplicate IP on the network..try pinging and then looking at your arp cache (arp -a) and see what MAC addy it's showing.  Then do a lookup at www.coffer.com/mac_find/ and see if it shows as Dell.

Otherwise, what noah said, get console access to it and restart the mgmt agent.
