For my ELK Stack, I am using a self-Signed Certificate Authority. I have shared my CA certificate to all my linux agents and stored them under /etc/certs and they can work. However when I install them on my windows as a fleet server, they refer back to the /etc/certs directory and because they cannot find it, the fleet server on windows does not work.

Can offer some advise on this?

Can you provide more context on how are you installing it on windows?

Also, share the log error you are getting?

How many fleet servers are you installing? Any reason to install it on windows instead of a Linux machine?
