I use apparel in vps server Arm oracle. I installed correctly apparel but i'cant add domain.

1) I have that error to set THE LISTENING IP:

Sorry, something went wrong：
Traceback (most recent call last):
File "class/flask_sockets.py", line 30, in call
handler, values = adapter.match()

raise NotFound()
werkzeug.exceptions.NotFound: 404 Not Found: The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

During handling of the above exception, another exception occurred:
