Client web socket error in log on exit of web ui ssh sessions

[stevenGravy]

Expected behavior:

Exiting a web session that is successful does not produce a error in the log.

Current behavior:

Upon exiting a ssh session from the web ui this appears in the log. No specific messages are occurring in the browser console. Confirmed on multiple browsers.
