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

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

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

weird error - does this consistently happen to you, or was it a fluke?

did not receive a valid HTTP response does not seem like something that this bot can address

If it keeps happening I'd suggest upgrading to at least python 3.10, and then maybe come back with some more information about what PS server you are connecting to.
