iOS Question Error on starting B4i-Bridge

[AHilberink]

Hi,

Just started using B4i after longtime only B4A.

I am using Hosted Builder.
I followed the instruction video and succeed in compiling a B4i-Bridge and install it on my iPad.

I got the following message:
Verification of app impossible
Internetconnection is needed to check trust of this developer.
(translated from Dutch)

What could this be? Which step did I missed? Internet is working fine on my iPad.

Kind regards,
André
