Error: unable to process update Request in Configure "Event Source File"

Error: unable to process update Request in Configure "Event Source File"

Hi,

My lab Contain these objects:

1.       Server 2016

2.       Event log analyzer Version 12.0.5 (created in virtual machine on vmware 6.5)

3.       Ethernet network with some switches and vlans

4.       Target servers created in Vmware 6.5 u2 as virtual machine

When I want to added some devices (for example windows 10, server 2016, Cyberoam UTM) to event log analyzer and I am going to configure "Event Source File" for them from this path:

Settings → configuration → manage device→ windows device→ configure event  source files

We encountered the following error:


I had check solutions and all of them are true.

I have implemented this scenario in my private lab as the same conditions:

5.       Server 2016

6.       Event log analyzer Version 12.0.5

7.       Same  credential (same domain and same user & password)

Therefore I had no problem in this scenario in my private lab!!!!!!

So, please be kind to let us know your advice  for such problem?
