Open LMS Session from client host

Question

Dear all,
i have a LMS application installed on a server X, the campus manager version is 3.2.
the application version is pretty old, but it is just working fine.
LMS is opening normally from the server itself.
My problem is that if i try to open Campus Manager/Topology services from a host different than the server itself a java screen opens mentioning trying to connect to ani server, and it just freeze and do not proceed. if i reopen from the server itself it works fine.
the server and the client host are on the same vlan, so no network access limitation exists.
Note: When i open the http request on LMS server from the client side, i authenticate and enter to the app normally but if i try to open the topology services or path analysis it do not proceed.
While checking the logs i found that it is like denying the Client Host name or IP Address.
please find log attached.

Dear Afroj,
Concerning the above mentioned debug steps; i don't find the option in the sequence on my server.
Point 1)      I can find LMSHomeScreen --> ServerConfiguration --> Setup --> ANI ServerAdmin --> DebuggingOptions
Point 2) & 3) I Select "Enable tracing on the selected modules". From the drop down list i check the "Trace enable" check box for the Module "topo".
       On the same page down, i check the "Record trace messages in log file", i enter the name and the path for the log file, C:\ANI_Debug
       And i press  apply,
Point 4) & 5) From here i am not able to continue, there is no button to start debug nor under LMSHomeScreen --> ServerConfiguration --> Setup --> ANI Server        Admin --> Debugging Options nor  under LMSHomeScreen --> Campus Manager --> Topology Services
  There no path Campus Manager --> Admin
Point 6) How to run a new data collection?!
Point 7) if i enable "debugging" of java from control panel and i select to "show" java console, how to view Java Logs?
Thank you for your help
