There are a couple of cron jobs that do not appear to be running. It may be that the snapshot cron is also affected.
I can see an error on the cron panel.
There was a problem spawning a call to the WP-Cron system on your site. This means WP-Cron events on your site may not work. The problem was:
cURL error 28: Operation timed out after 3001 milliseconds with 0 bytes received
When working with WP-Engine we temporarily deactivated the WP-Defender plugin and this error disappeared.
But the cron job still didn’t seem to run for Snapshot.
