Fiori Wave 2 Launchpad HTTP 511 Network Authentication Required

Dear expert,

When I try to call the Fiori launchpad, it returns the code of HTTP 511 Network Authentication Required. BEFORE the login screen shows.

Also error: GET /sap/bc/ui5_ui5/ui2/ushell/shells/abap 401 Unthorized.

However if I maintain the ushell service in SICF on LOGON DATA tab with a specific user A103296.

The homepage(with error "unable to load groups") comes out directly without the login screen.

For "unable to load groups", it says  401 Unauthorized for PAGE_BUILDER_PERS.

However I have both the authorization SAP_UI2_ADMIN_700 and SAP_UI2_USER_700 for A103296.

I suppose there's no need to maintain the logon data for SICF service,right?

On the other hand, Launchpad Admin screen runs smoothly without any issue.

Could you please help on this?  Masayuki Sekihara

Thank you very much indeed!

Thanks,

Chloe
