websockets.exceptions.InvalidMessage: did not receive a valid HTTP response

[zuils]

Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/websockets/legacy/client.py", line 135, in read_http_response status_code, reason, headers = await read_response(self.reader) File "/usr/local/lib/python3.8/site-packages/websockets/legacy/http.py", line 122, in read_response raise EOFError("connection closed while reading HTTP status line") from exc EOFError: connection closed while reading HTTP status line

The above exception was the direct cause of the following exception:

This was using nash_equilibrium and building with docker, never happened to me before
