What ports need to be open when using the Crosser node?

Answer

The Edge node communicates with the Crosser Cloud service using HTTPS on port 443. The HTTPS port is also used by many modules that connects to web services. All traffic is initiated from the edge node, so this port must be open for outbound traffic. Locally port 9090 is used for inbound HTTP(S) traffic to the HTTP Listener module and port 1883 / 8883 for inbound MQTT traffic (MQTT Sub Broker/Client modules). The local web UI and API is accessed through port 9191. Inbound port mappings are configurable.

My career started in the academic world where I got a PhD in physics by researching large scale data acquisition systems for physics experiments, such as the LHC at CERN. After leaving academia I have been working in several tech startups in different management positions over the last 20 years.

In most of these positions I have stood with one foot in the R&D team and another in the product/business teams. My passion is learning new technologies, use it to develop innovative products and explain the solutions to end users, technical or non-technical."
