Engines created on tenants use a different encryption handshake for each tenant and connect back to the tenant through the main host server.
Configure the base URL.
On the tenant, go to→ → .
In the Base URL (for D2 Agents and Engines) field, enter the external tenant URL address in the following format:
<main account external address>/
<tenant account name>
Download and install the engine.
Go to→ → .
Click Create New Engine.
Select and download the appropriate installer file.
Install the engine on the appropriate remote machine.
Go to→ → and verify that the engine is connected.
In many cases the Cortex XSOAR server has a firewall because the engine is probably installed in a different network. The firewall might stop any communication between the engine machine and the Cortex XSOAR server.
Ensure that the engine machine is able to communicate with the main host server. You can use Telnet, or any similar tool to check the engine has access to the main account before you install it. If there is a firewall you may need to allow access from the machine that hosts the engine, so that it can communicate back on port 443 (or any other port the main host may use) or set an ANY ANY rule.
