Unable to view tempo after site setup

Hi all,

 

I am installing a new site with HA configuration (separate 3 hosts for DB, Web & App, and Engines & data server & search server respectively; so far no share folders/logs are configured yet),

and I have successfully changed the password for first Admin login.

 

However, I ran into a problem of blank tempo page, but other pages (e.g. admin console and designer) are showing right.

abnomal tempo

normal admin and designer

  

 

Do you have any idea of this?

 

Thanks in advance.
