SignalR exception thrown by Task: System.AggregateException

I am getting this error in my logs now and than. Is this something I have to worry about? It is kinda a long error and clutters the log.

It just means the browser was disconnected and a UI notifcation was sent from the server to the client (thats no longer there), we’ve been working on preventing them to the logs aren’t getting hit with errors that aren’t really errors. I’ll add this one to the list.

Edit: Fixed in develop
