If you use a proxy server, you must register the proxy server as an external service using ARIS Cloud Controller. For further information, refer to the ARIS server Installation - Windows or ARIS server Installation - Linux document.
If you use multiple connections to third-party document management systems, where only some connections need the proxy support, add any hosts that do not require a proxy under nonProxyHosts.
Example
register external service proxy host="10.60.11.160" port=6588 nonProxyHosts="localhost|127.0.0.1|vmeswin01"
