OMSA 8.3 @ ESXi 6.0 U2 @ R515 -> Can't login into OMSA web site at ESXi HOST.-

Hello Guys.

I updated my ESXi from 5.0 U3 to 6.0 U2 and I lost my OMSA. I can't log in from the web page.

For Updating the Host, I used this ISO file:
. VMware-VMvisor-Installer-6.0.0.update02-3620759.x86_64-Dell_Customized-A00.iso

After that, I installed OM-SrvAdmin-Dell-Web-WINX64-8.3.0-1908_A00.EXE at a W2012S VM at that Host. I can open the web site for login, but when I try to connect to my ESXi HOST, I received this message: Failed login ... connection error.

When I saw that, I started to check some stuff, I ran: "esxcli software vib list" and saw:
Name Version Vendor Acceptance Level Install Date
----------------------------- ----------------------------------- ------ ---------------- ------------
...
OpenManage 8.3.0.ESXi600-0000 Dell PartnerSupported 2016-07-29
dell-configuration-vib 6.0-2A00 Dell PartnerSupported 2016-07-29
iSM 2.3.0.ESXi600-0000 Dell PartnerSupported 2016-07-29
...

Another thing very strange for me, is that I can't see any reading from the server sensors at web UI: HOST/.../ or Vsphere Client.
But, I can read a lot of the data from Idrac web page and ESXi SSH using "esxcli hardware ipmi sdr list".
