Problems displaying JOSSO atricore-console

I installed JOSSO2 into CentOS 7 :

$ java -jar josso-ce-2.4.4-39-20200219.142717-unix.jar -console
 

I start the service with the command below :

[root@amanda-server josso]# /usr/local/bin/atricore
atricore: Clearing OSGi plug-ins cache ...
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0

However, when I open the page in a few browsers (Mozilla, IE & Chrome) i see a blank page (image attached).

How do I resolve this problem? At first I got excited when I opened it in Google Chrome and it showed :

However, even after enabling Flash and checking that the version is updated, I still get the same problem.

Please help. I tried posting in SourgeForge JOSSO forums, however there is no reply.

I am rushing for a dateline to complete this task by 27/3/2020 on production. However, this is only in UAT.

My colleague advised to use browser developement console, and this was the error :

Failed to load resource: the server responded with a status of 404 (Not Found)

However, installing JOSSO2 is new to me, and I am not sure if any missing pre-requisites has caused this problem.
