Each port and its use is described below:

* `443` - Communication between Users and Orchestrator with the connected Robots. You can select a different HTTPS port for Orchestrator, if desired.
  :::note
  This port is open by default, unless closed by your security administrator.
  :::
* `1433` - The default port for communication between Orchestrator and the SQL Server machine. You can select a different port, ensuring that it is open in the firewall.
* `10000` - Communication between Orchestrator and the HAA.
* `9200` - Communication between Orchestrator and the Elasticsearch server.
  :::note
  This port can be opened for Orchestrator only, as no other machine can access the Elasticsearch server directly.
  :::
* `9300` - Communication between Elasticsearch nodes.
* `5601` - Default port used by Kibana. It must be opened on the machine where Kibana is installed.

## Not pictured above
* `3389` - Required for RDP automation, needed for HD Robots.
* `80` - Required for the Webhooks web service.
