Updated on April 6, 2022

Troubleshoot problems with REST connectivity by validating the REST endpoint.


You might see Connection refused in the log file.


The client firewall security is blocking the outgoing request.

Resolving issues with REST network connectivity

  • Confirm that you are using the correct port for the correct protocol.
  • Validate that you can reach the endpoint by using telnet, cURL, or Postman.
  • If you can reach the endpoint outside of Pega Platform, determine whether the external system firewall is causing the issue.
