Welcome @alexdzehil ! Are your websocket connections being made directly to daphne, or are they being proxied through nginx / apache / some other web server? Are you seeing any error messages in the daphne log? Is this limit you’re hitting _exactly_ 200 connections and _always_ 200 connections? Or is there any variability in that number? If it’s exactly 200, then I’d check the DigitalOcean docs to see if they identify any limitations for the service you’re using. (You might also want to ask them this question, because this would sound to me like some type of configuration limit.) ---
