I have checked the permissions on the folder itself, I can navigate to the volume on my Mac, I haven’t changed anything besides for a reboot of the machine. This folder is on a networked volume. It’s meant to be a simple flat file web server. The caddy file info is as follows…
Sure of course, somewhat simple but possibly overlooked.
If you upgrade to Catalina, a whole bunch of fun things get essentially blocked or cut off until you go into System Preference > Security > Full Disk Access, and check them to have access.
Caddy was listed, unlocked, checking, and then simply reloading the page, it worked.
