I have single server implementation of Librenms that is just not generating any notifications. Alerts trigger and are working but none of three notification types configured - email transport, browser notification transport and syslog transport are ever triggered.
I have tried all the troubleshooting options on the forums without any results. I have the same experience with 25.4.0-102 and 25.4.0-108. All the manual checks for each notification transport work flawlessly.
Any help is appreciated.
Here is the relevant data:
