Thank you for your reply.
The pool appears to be corrupted, and I keep getting a warning stating that the agent is "unknown (missing)."
There used to be a pool with about four VMs, and I was instructed to change the IP range. After changing the IP addresses for all components and reinstalling the agents, the agents have access to the connection server (CS). The VMs get created and join the domain, but they remain in the "unknown (missing)" state.
I even tried creating a new pool, but it stops during the initial process and displays the error: "Couldn't find /path/to/the/vcenter/vms."
However, when I use different vCenter credentials with the same privileges, the desktops are created without any issues.
