On my instance I started getting the occasional Invalid transport websocket errors, accompanied with Nginx 499 errors. This manifests itself by websockets basically crashing - chat clears out and voting not registering for others on sockets. Corrects itself after a while, then comes back.
@Polsaker mentioned this might warrant updating the project to suppor python-engineio v4 (along with upgrading pyton-socketio and flaskio).
Upon further testing the 499 errors may well be client-side doubleclicks on forms etc. Also I am no longer seeing the server-side symptoms such as sockets crashing.
