ConnectionRefusedError when running sanity checks

[bendoesai]

Trying to get this back up and running after putting the project down for a while. I did a fresh reinstall of OpenPlanet and TMRL but I can't seem to get the sanity checks to work. I know the plugin is working because I can reload it and see "Waiting for connection" appear (though with a deprecation warning, maybe that's part of it?). Everything will be running on localhost, so I've left config.json alone for now until I get it running. When I try to run --check-environment or --record-reward per get_started.md, the stack trace below occurs, then OpenPlanet times out.

I've also tried using the Gym environment interface, which is how I had it running in the past, but it fails silently when I try to run it like that (just an OpenPlanet timeout) and I have a hunch it's the same issue.
