Communication between iPhone (iOS10) and nifty mobile backend

Currently, there is an application developed using monaca and nifty mobile backend.
When I updated iOS to 10.0.2,
from nifty mobile backend Data retrieval is no longer possible.

Update SDK version to 2.1.3 by referring to the following page
I tried, but this also didn't solve the problem.
　https://github.com/NIFTYCloud-mbaas/ncmb_js/issues/165

The error content is
　Error:cannot GET https://mb.api.cloud.nifty.com:443/2013-09-01/classes/****

That's right.

How can I solve this problem?
