It seems gotty.jp clears Local Storage on the browser.
https://github.com/yudai/gotty/blob/master/resources/gotty.js#L20
Is there any reason to do so?

I am using Gotty over a reverse proxy with a multi-factor authentication.
For my case the authentication uses Local Storage, so clearing Local Storage causes problems.

I have commented out the line, and so far it looks working fine.
