The SAP Cloud Connector user interface is not available on default  URL (https://localhost:8443), the browser shows an empty screen.

To get more details about connection establishment, activate SSL trace, see link
How to enable SSL trace in SAP Cloud Connector

In <drive>:\sap\scc20\log\ljs_trace.log look for the reason of the connection error, look for http-bio-<port number>-exec thread:


#http-bio-8443-exec-2#          #, SEND TLSv1.2 ALERT:  
#http-bio-8443-exec-2#          #description = handshake_failure|
#http-bio-8443-exec-2#          #fatal,
#http-bio-8443-exec-2#          #description = handshake_failure|
#http-bio-8443-exec-2, IOException in getSession(): no cipher suites in common|



The "no cipher suites in common" message means that browser and SAP Cloud Connector could not agree in a common cipher suite during handshake.
