When I am running zap in local it runs complete scan without any issues while when I run zap installed on an ec2 instance it fails with an error

Question

Zap can be accessed publicly on ec2 instance using IP and PORT.

The error I received:

Proxy error: HTTPConnectionPool(host='10.102.0.156', port=8080): Max retries exceeded with url: http://zap/JSON/ascan/view/status/?scanId=0 (Caused by ProxyError('Unable to connect to proxy', NewConnectionError('<urllib3.connection.HTTPConnection object at 0x0000028E18540940>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it')))
