Why have n8n triggers unexpectedly stopped working?

Hello!

I’m experiencing an issue with n8n: the triggers in my workflows have suddenly stopped working without any apparent reason.

I’ve already tried the following steps to diagnose the problem:

1. Checked n8n Logs:

   • No errors related to triggers or workflows were found.

2. Reviewed Server Health:

   • The server is stable with sufficient CPU, RAM, and disk resources.
   • The internet connection appears to be stable.

3. Verified n8n Operation:

   • The web interface is accessible.
   • A restart of n8n did not resolve the issue.

4. Examined Trigger Settings:

   • Triggers are activated.
   • Webhook and cron expression settings seem correct.

5. Checked Server Time Zone:

   • The server’s time zone is set to Europe/Moscow
   • Time synchronization with NTP is functioning properly.

Additional details:

• n8n Version: 1.75.2 (latest stable version)
• Trigger Types: Webhooks and cron expressions
• Server Operating System: Ubuntu 22.04
• Database: PostgreSQL

I have a few questions:

1. Could recent updates to n8n have affected trigger functionality?
2. Are there any known issues with triggers in version 1.75.2?
3. What other diagnostic steps can I take to pinpoint the issue?

I’d appreciate any advice or troubleshooting suggestions. Please let me know if you need more data like logs, screenshots, or configurations.

Thank you for your help!
