Protocol

obnizOS uses Websocket (TCP) to communicate with the cloud.

Router limit

Depending on your network device, you may not be able to use Websocket. The following is a workaround.

Using TLS communication

In most cases, only plaintext Websocket is inhibited, so you can connect to it by using TLS (SSL) communication.

For more information on TLS, please see below.
