From release 10.2.1.1, you can configure HTTP proxies from the Client ID Configuration page.

When HTTP proxies are configured, the Avaya Aura® Device Services use the HTTP proxy to dynamically discover the metadata about the OpenID Connect (OIDC) provider if the OIDC URL is not directly accessible.

Specify the proxy in the following format: <PROXY_HOST>:<PROXY_PORT>. Providing incorrect inputs reject the entry, and an error message is displayed on the Avaya Aura® Device Services administrator user interface.

However, if no proxy address is configured, the OIDC discovery uses the OIDC URL directly, without any HTTP proxy.
