    I assume you mean Snort 4.0_8 has been working for you and then just suddenly started not working. If so, then read on.

    This is almost always caused by a rule syntax error (or could be a required preprocessor is not enabled). Look in the pfSense system log and you should see a Snort error message that will tell you what's wrong.

    When the rules update (usually twice each week) it is entirely possible for either a rule to be published or updated and have a syntax error in it, or a rule that was previously default-disabled by the Snort team might have been changed to default-enabled by an update. If that particular rule need a preprocessor enabled that you have disabled, that can result in a startup failure.

    So check the pfSense system log to see why Snort is not starting. Post back here if are not able to identify the cause.
