Symptom

"Connection refused"
Environment
Boomi
Resolution
Outbound communication from atom server is allowed only on standard port 443 for HTTPS protocol and 80 for HTTP protocol.
If after adding into allow list on atom server IP address also, your calls are failing do check if communication is allowed on port 443/80 from your end as we support only these 2 ports due to security reasons.
