If you are using a proxy server in your network, you must configure the proxy server in vRealize Suite Lifecycle Manager.
Normal Proxy (with or without Credential) as well as Proxy with AD configuration, are supported by vRealize Suite Lifecycle Manager as of now.
Prerequisites
You must have installed and configured a proxy server in your network before using it in vRealize Suite Lifecycle Manager and the proxy server IP should have a host name that is resolvable from vRealize Suite Lifecycle Manager appliance console.
Note: If the proxy server does not have a resolvable host name then the procedure to add proxy fails.
