Drupal 6 cron job fails
I have had a cron job running for Drupal 6 successfully for many months. It suddenly stopped working 2 days ago, sending me the following error every time it tried to run: [ curl: (7) couldn't connect to host ]. The old, previously working job was [ curl -A 'Mozilla/5.0' -sS http://subdomain.mydomain.com/cron.php ]. I can't even run cron manually from Drupal anymore! What should I change to make it work again?
