Web UI Error Internet Explorer cannot display the webpage

Hi Gurus,

I'm facing a problem to access WEB UI.

When I go the transaction  CRM_UI, I'm getting the blank screen in the browser with the next message:

"Internet Explorer cannot display the webpage"

http://crm.grupoxxxxx.com:8000/sap/bc/bsp/sap/crm_ui_start/default.htm?sap-client=001&sap-sessioncmd=open

The problem occurs only in the PRD server, the others clients are ok.

All services in SICF transaction are ok.

I registered my IP address  in HOST file (path: drivers>etc>host)

But the problem persist.

Any suggestion?

Immediate help will be highly appreciated.

Regards!

MC
