Error during Access Mobile connection

Hello,

We are on BI 4.0 SP2 Patch16 and SAP BO Mobile App is on version 6.1.7.

we are setup as in the following link:

Setting up SAP BusinessObjects Mobile - Business Intelligence (BusinessObjects) - SCN Wiki

We tested the correct deployment of the war files by using this link http://servername:8080/MobileBIService/MessageHandlerServlet?message=GetVersion and below is the screenshot:

We created the connections as per this document but on android How to Connect SAP BO Mobile to a BI Server 4.0

but we face MOB 06031 errors.

Note: we can access the servername:8080/boe/cmc from android explorer.

Regards

Said Shepl
