The Eclipse IDE desktop application shows an error stating that it is unable to connect to the URL when accessed from WSS protected machines.
The issue is due to the SSL certificate validation. When WSS intercepts SSL, it sends its own certificate chain back to the application but the application is expecting the website's actual certificate chain.
The WSS Cloud Root Certificate is not in the Eclipse store therefore the certificate validation fails..
You can make the Eclipse IDE application to trust the Windows Root Certificate Authority Store (where you already have WSS root certificate) by following the steps below;
-Djavax.net.ssl.trustStore=NUL
-Djavax.net.ssl.trustStoreType=Windows-ROOT
