Whenever I try to put Moodle 3.3.2 in Maintenance Mode, non-logged in users get a 404 error message.
The error logs indicate that maintanance.html is missing:
2017/09/13 19:55:22 [error] 23151#23151: *3047 open() "/home/mysite/moodle/maintenance.html" failed (2: No such file or directory) while sending to client, client: 2601:3c4:201:658f:383d:352c:e7e2:1ae3, server: edu.mysite.xyz, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "edu.mshealthcarealliance.org", referrer: "https://edu.mysite.xyz/"
That file does not exist in the moodle folder or sub-folders in any version I have had.
Any idea why this is happening and what I can do to resolve it?
