KeyError: Key not found: sec-websocket-accept in ubuntu

i have invoke cli with below command

sudo ./acli-linux-x86_64 -u http://localhost:3000/cabel -c waiting_room_channel

[palkan]

That means that the server response doesn't contain the sec-websocket-accept key.

Isn't there a typo in you url? cabel -> cable

@palkan Thanks
