Can't get cloud agent to install

New OPNSense build on an old Dell server. OPNsense 23.7.5-amd64. Zenarmor Version: 1.15.1 - Sep 29, 2023 11:58 AM. Trying to install the cloud agent, and it just hangs on "Please wait... Cloud Agent is being installed..." No ideas on where to go from here, any help would be appreciated.
