76.1 update caused 502 Gateway issue

Running 76.1 on an Ubuntu server using Docker. Pulled the new image, restarted and boom 502. Nothing else changed and the server is serving everything else up properly. No obvious errors in the logs seems to be an issue with NGINX or Docker. Anyone else running into this?

Looks like its related to Chromecast… pychromecast.socket_client failing. It also looks like Im not the only one experiencing this. Pretty dumb that the front end won’t load because of a shitty component.
