Detail

Hello, I am having issues adding a fleet server and adding an endpoint to my SO environment.

I am using the following information to build each node (master, search, sensor)
4 CPUs
20GB RAM
4TB

The appropriate NICs we provided to each depending on their role.

I was able to get the setup done properly without an issue.

I have logs, am able to import caps, and able to see all IPs within the network I chose during setup.

Config Changes Made:
I added the Endpoint's subnet to the Firewall > Hostgroups > Fleet section and saved it

No other configurations were made.

My issue is when I am trying to add a fleet server:

I initially used the MGMR node as the default fleet address and ran into an issue when trying to run the command that requires being added to the endpoint:

I changed theURI to https and got the following error:

I did this because when I ran the compiled command I kept getting an error: Therefore, I attempted to just download the file to see if that would work:

This did not work:

My work around was to download the file to my endpoint and run the remainder of the command:

I extracted the tar file for windows

I ran the finel "elastic install" command and this is the output.

I have successfully build a standalone and ran into the same issue :
Pictured below:

NOTE:
I have updated the settings to https for the host
I am not going through a proxy
My firewall rules are not blocking any configurations
I have attempted both http and https just to be sure

I am stuck here. I am not sure if this is a certificate issue because I thought elastic makes its own certificated during initial setup.
Any help would be greatly appreciated.
