The browser tab for the web page for one of my Syncthing nodes has an exclamation point in a black circle. I presume this indicates an alert. I don’t see anything obviously related in the log.
Where do I go to see the current alert (or whatever else the icon indicates)?
The tab icon is usually cached by the browser, i.e. it doesn’t necessarily correlate with the actual current state. If there’s nothing out of the ordinary in the web UI or logs, then you’re fine.
