Ocs Server (2.6) doesn't see any Computer

Hi !!

I have installed (replaced old server) with OCS 2.6 in ubuntu 18.04, but no Computer (Windows) are registered

Img 1: Server information

Img 2 and 3: Showing that I can enter web ocs service

Img 4: Configuration from Windows Agent (.ini and .log from ocs inventory agent) 

Img 5 and following:  (ServerSide) Some posts related talk about mod_perl.  I have installed and configured mod_perl as you can see below

Apache 2 - Access log

mod_perl configuration

Showing that is enabled and in the correct folder

and configured.

Thanks in advance.
