Hi, I’m trying to test my MQTT broker on a droplet, but there seems to be a limit of max simultaneous connections somewhere.
Running tests (using mqtt-stresser) from inside the droplet or even from droplet in different region, I can hit 15k simultaneous TCP connections. But running tests from my computer I can hardly get more than 500. Then, no new connections are accepted (time out). Maybe there is a DDoS protection in DO infrastructure that limits max connections from singe IP address?
