Based on the analysis the Dynamic Tag Management(DTM) cloud connector is not using the the proxy server details configured to establish the connection.

This is the defect with the connector, raise a ticket with Adobe support team to receive the fix.

As a temporary fix update DTMConfigurationUtil.java in bundle - /libs/cq/cloudservices/install/cq-dtm-0.1.8.jar to support proxy server while establishing the connectivity.

DTMConfigurationUtil.java - callDTMApi

HttpHost proxy = new HttpHost("proxy.com",80);
RequestConfig config = RequestConfig.custom().setProxy(proxy).build();
apiRequest.setConfig(config);
