Hello - I read the requirements carefully and installed Otto on two different Mac servers (with FQDN/SSL Certs) and both failed.
The terminal breadcrumbs did not yield any clues, so I also tried starting the service via Terminal, rebooting, and a manual installation (downloading/executing the installer).
I also noticed that when checking Full Disk Access permissions that Otto does not appear in the list.
I will upload the terminal session from the install and some screenshots in case that helps.
macOS 14.7.2 [latest build of Sonoma]
FMS v21.1 [latest]
Also - not sure if Otto is supposed to install a .fmp12 file to be hosted by the server - did not see that in either case.
(only one screenshot allowed, so I chose the terminal session)
Thank you!
