Error: undefined socket will be closed

Has anyone run into this error while using secure websockets in WebGL? I have a product that is using wss to connect to a game server hosted in AWS Gamelift. It creates some pretty gnarly, long urls so I’m wondering if maybe an antivirus/webshield program is aborting the connection. Or perhaps it’s some issue I haven’t accounted for. I do have nginx setup as a reverse proxy on the game server if you were wondering how WSS was working.

Thanks for any insights.

This is the first time I see the issue. Where do you see the error happen? Can you post a screenshot and/or logs of the error?

Are you able to temporarily disable the antivirus program to see if it makes a difference?
