Problem
If Domibus is running on Java 8 version 111 and above, and the application has Proxy settings enabled, then on invocation of HTTPS URLs through the proxy, Domibus might face the error:
Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"
Solution
This is because basic authentication to proxy server has been disabled by default from Java 8 version 111 onwards.
Re-enable this setting by adding the environment setting -Djdk.http.auth.tunneling.disabledSchemes="" on start-up script of each managed server.
