WebDispatcher NW-7.45 with NWBC, "could not retrieve navigation information from any role"

we installed new WebDispatcher:

SAP WebDispatcher NW-7.45 on Linux 64bit (Cent-OS 7),

using with NWBC 5.0 SP10,

Error "could not retrieve navigation information from any role from the server for your user"

but using our "old" WebDispatcher NW-7.00 PL140

with the same user and the same ECC-system, NWBC-session works fine.

how to resolve this issue?
