Here’s one of our small wins this month 🎉
We recently ran into an issue where email alerts from our Celonis Action Flows stopped triggering. After some investigation, we discovered that the problem originated from the SMTP connection being used for sending email notifications.
The tricky part was that the issue wasn’t immediately obvious. Even after engaging Celonis Support and the SMTP (TMS Product) team, it was difficult to pinpoint the exact cause due to limited visibility across systems and teams. Eventually, we identified that a network configuration change had restricted outbound traffic on specific ports, which broke the SMTP connection.
Once the correct port was re-enabled for our SMTP setup, everything started working again. ✔️
It might sound like a simple fix, but coordinating across teams and diagnosing the issue with restricted visibility made this a challenging one. Still, we managed to resolve it — and that’s definitely a small win worth celebrating this month! 🙌
