**Your software**

- **My Mautic version is:** 4.x.x (installed on Apache2, Ubuntu EC2)

- **My PHP version is:** 8.0.30 (CLI)

- **My Database type and version is:** MySQL 8.x

- **Other details:** PHP CLI timezone set to `America/Detroit`, Mautic System Default Timezone and User Profile Timezone both set to `America/Detroit`. Cron jobs are configured under `www-data`.

**Your problem**  
I’m trying to schedule a campaign to send at a specific time. Cron jobs are firing as expected, the campaign is published, and contacts are in the source segment — but **no emails are being sent when the campaign publish time arrives**.

Here’s what happens:

- Segment is non-empty (confirmed via UI and SQL).

- Campaign is published with **Publish At** set for \>10 minutes in the future (so cron has time to run).

- At the scheduled time, I see in the logs that cron runs `campaigns:trigger`, but it always shows `0 total events were executed`.

- Sometimes contacts don’t even get added to the campaign automatically before the publish window, even though `segments:update` and `campaigns:update` cron jobs are running every 10 minutes.

- If I manually rebuild (`--reset`), contacts still don’t get processed.

If I use a **Marketing Email** that was already sent to those contacts, I understand Mautic will skip it. I cloned the email (new Email ID), republished, cleared cache, and rebuilt the campaign — still no events fire.

**These errors are showing in the log**  
`/var/log/mautic_camp_trigger.log`:

```auto
[2025-09-23 01:43:02] Triggering events for campaign 32
[2025-09-23 01:43:02] Triggering events for newly added contacts
[2025-09-23 01:43:02] 0 total events(s) to be processed in batches of 500 contacts
[2025-09-23 01:43:02] 0 total events were executed
[2025-09-23 01:43:02] 0 total events were scheduled

```

No fatal errors or exceptions in `var/logs/prod.log`.

**Steps I have tried to fix the problem**

1. Confirmed cron jobs are running:

2. Cleared cache after any config or time changes:

3. Manually rebuilt segments and campaigns with verbose + reset:

4. Verified:

5. Cloned email to avoid duplicate suppression, republished, reattached in campaign, reset membership. Same result.

6. Mail transport test email works from Configuration page.

- Is there any scenario where `campaigns:rebuild --reset` would not re-enroll contacts even though they are in the source segment?

- Could this be a timezone save/convert issue where the campaign is not actually active yet (even though UI shows it as published)?

- Are there known bugs in Mautic 4.x where Publish At + close scheduling window causes membership to miss and no events fire?

- Besides duplicate email prevention and frequency rules, what else could cause Mautic to show 0 total events at trigger time?

Would appreciate guidance from anyone who has debugged campaign membership assignment and event execution timing issues like this — especially around campaigns that are published close to their send window.
