Websocket Unobserved exception in Task

Sometimes the websocket server disconnects (what to me seems randomly). I couldn't figure out why this would happen but here is what I see in the log file.

2026-07-18 19:26:42.085 +02:00 [ERR] Unobserved exception in Task.
System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. (I/O operation aborted.)

```

The report names only the websocket server and the logged Task exception; no source file or test is identified. Start by locating the websocket server and the code that creates or awaits its socket tasks, then reproduce the disconnect while capturing the exception. Done means the disconnect cause is understood and the unobserved exception is handled or prevented.
