HI,
Were you able to resolve this issue?
I have the same issue. The URL https://<servername>:8443/dswsbobje/services/listServices throws an internal error on expanding Serices.
We are on BO4.1. recently changed from http to https using CA certificates. All links to all web applications are working fine except for dswsbobje. We do not have design studio and we do not use it. But the url http://<servername>.8080/dswsbobje/services/listServices was working fine and displayed all services.
Only after changing to https we are seeing the issue. Can anyone pls suggest possible solution to this. I am curious to see what broke with https vs working fine with http though we did not have Design Studio installed.
