Alerting emails stop unexpectedly

And your database connection in Ignition isn’t configured for failover? I can’t see any immediate problem with your expression, but unfortunately the log messages don’t include the severity. Are those tags set for “High” severity?

The questions about failover & replication pertain to the fact that the distribution groups get reloaded often, and if the database had failed over, it’s possible that the current target might not have them for some reason. However, the UI in the gateway also uses the same data, so since they show up there, I can’t imagine it’s that (unless some sort of error is happening on the load that we’re not seeing).

So, to be clear: these distro groups work with these alarms (say “SQLTags.default.Kill Floor Main PLC/Clean Side Stops/Dress Stop Manual Split Station.Dressing Line Stopped at Manual Split Station” for example), and then after some days stops?
