Websocket connection disconnects every 3 heartbeat

Hi, we have a phoenix app (elixir) on Fly using websocket with heartbeat every 30 seconds. Socket connection disconnects every 3 heartbeat. No errors on server log, only “CONNECTED TO” log from client every 90 seconds.

Not sure if there is any issue on Fly websocket connection handler?

Yes. I just noticed this. We’ve added some abuse mitigation strategies that are interfering with long-lived connections.

Working on a fix right now.

@fifwb This should now be fixed. Please let us know if that’s not the case!

I saw It’s fixed over an hour ago! (so I marked the solution). Right now it’s working as usual. Thank you.
