How RPA Agent connects with Appian

Question

How does RPA agent connect/communicate with orchestration server ? 
 Is there any specific ports need to open - considering the agent is internal to company's infrastructure and the appian is in cloud..

Hi ravib0008 , Appian RPA uses a client-initiated communication model . 
 The RPA Agent communicates over HTTPS (port 443) . 
 The RPA Agent (robot) installed on your internal server or desktop:

Initiates the connection to the Appian RPA Orchestrator (hosted in Appian Cloud).

The Appian Cloud Orchestrator uses a signed SSL certificate. 
 
 Sends logs, status updates, and receives instructions&mdash;all over outbound HTTPS .
