On the portal you might see that the firewall is indicating as being "delayed".
This can happen due to a few reasons:
Scheduled tasks are not running properly on your site. We attempt to ping our API from your site every hour. However, since WordPress scheduled tasks run when you have visitors on your site, this might not happen if you have no visitors on your site. It is also possible scheduled tasks are not running at all on your site even when you have visitors due to an error. You can use a plugin such as WP Crontrol to keep track of your scheduled tasks.
You do not have the right API credentials configured on the license settings page. The API credentials which you can find on the portal under your site > Site Settings > API Keys should match the API credentials on your site at wp-admin > settings > security > license page.
One potential solution to reason 1 is to use a server based scheduled task which triggers your scheduled tasks even when you have no visitors.
Disable the default WordPress cronjob by adding the following to your wp-config.php file in the root folder of your site:
Setup a cronjob in your hosting account management panel. In CPanel this can be found under Advanced > Cron Jobs.
Set the interval to something between 5 and 15 minutes.
Set the cron command to the following (change the URL to your own):
wget -q -O - https://examplesite.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1
Now click on the create new cron job button.
