Hi guys,
I faced the same issue and was able to resolve it using the steps provided in SAP Note - 1757812 - Exception condition "URL_PATH_IS_NOT_SUPPORTED" is raised when logon to WebUI or IC WebUI.
The key missing services were:
/sap/bc/soap/ici_ssl
/sap/bc/bsp/sap/sam_sess_queue
/sap/bc/soap/ici
Hope this helps someone else!
Regards,
Nelson
