Failed to execute 'atob' on 'Window'

[luggscheb]

so I just started up the index.html,
installed the wsproxy which seems to work fine

As I tried to connect to my pi it got stuck on "connecting...",
I looked in the chrome console and I saw this:

Uncaught DOMException: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.
    at WebSocket.ws.onmessage (http://my_ip:82/SSHy/index.html:235:31)

should I try to make it work without the WebSocket or is there another fix
