Required Open Ports

I’m setting up a whitelist of open ports for our IoT device. Does anyone have a list of required open ports for the Losant platform to work.

Hey @PhillipKB,

How your devices will connect & communicate with the Losant Platform will dictate which ports you will need to whitelist.

That being said, here’s a list from our documentation:


  • TCP— 1883
  • TLS— 8883


  • WebSockets— 80
  • Secure WebSockets— 443

You will likely only need to whitelist one port depending on your use case. If you’re using MQTT, I would highly recommend you use port 8883.

Thank you,
