[FORTISIEM] WINDOWS Agent Disconnected

[adrifesa95]

Hi Team,

I have installed windows agent in test server and that is working fine after doing all the troubleshooting.

But issue is that when I installed the agent in production server, all agents are showing disconnected.

I have researched a lot about this issue but not getting help. 

Version is 7.2.2

I have tested connectivity between agents and collector and supervisor.

Request you to please help in this situation. Thanks in advance.

Hi Fortinet Community,

I’m still actively working with the customer and have already performed all possible troubleshooting steps, but the issue remains unresolved. Any further guidance or support would be greatly appreciated.

Thank you in advance!
