On my server, without ever changing anything (manually):

# pwd
/var/lib/vpn-server-api
# ls -l stats.json
-rw-------. 1 apache apache 1835 May  8 00:02 stats.json

It is updates from cron:

$ sudo cat /etc/cron.d/vpn-server-api
RANDOM_DELAY=10

@hourly apache /usr/bin/vpn-server-api-housekeeping
@hourly apache /usr/bin/vpn-server-api-disconnect-expired-certificates
@daily apache /usr/bin/vpn-server-api-stats

The cron is run as the user "apache". If you manually want to update the
"stats" file, you can use:

$ sudo -u apache /usr/bin/vpn-server-api-stats

There is one other reason why the stats won't update: PHP runs out of
memory. If you have many users, it can be there is not enough memory
available to run the stats script... You see that when you manually run
the above command, it will error out.

You can update

memory_limit = 128M

in /etc/php.ini to e.g. 512M

(Yes I know, this stats script is really stupid and really shouldn't use
this much memory...).
