Now our basis provide a PO 7.5 system with only HTTPS connection (https://ip:50001/nwa). When i do the system initialization, there is an error in SLD content creation. For system use http port 50000 to connect to SLD. After i finished the initialization, i find only http connection to ESR and ID in /dir/start/ page. So ESR and ID cannot opened.
My question: does it mandatory to use http protocol in PO? any document describe it?
