Did I get kicked out of the Server? Kicked from Server. Host closed the connection.

No, you didn't get kicked. This is a common issue with The Isle Servers and Steam Connection. The problem occrus from your end and it's the result of a bad internet connection or a temporary Steam outage in your area. It resolves it self - most of the times.
