Summary

User has configured both internal and external integrations. While configuring the below proxy settings in JVM arguments, the internal integrations fail.

-Dhttp.proxyHost=xxxxxxxxxx \
-Dhttp.proxyPort=8080 \

Error Messages

Requests are rejected as the external application has only whitelisted the proxy IP address

Steps to Reproduce

Invoke external services using the Connect REST service.

Root Cause

Currently, Pega does not support proxy settings explicitly for each connector. It only supports JVM level arguments for proxy settings.

Resolution

Perform the following local-change:

Use the below JVM arguments, if www.example.com:80 proxy host is used for both HTTP and HTTPS and the internal sites must be excluded in domain pega.com:

-Dhttp.proxyHost=www.example.com
-Dhttps.proxyHost=www.example.com
-Dhttp.proxyPort=80
-Dhttps.proxyPort=80
-Dhttp.nonProxyHosts=*.pega.com

Note: HTTPS also uses the http.nonProxyHosts setting
