REST Api issue iis

Hello, when I try to configure LIvechat 3 IOS app, I get the following errors, as shown in attachments. I use IIS 7.5 webserver.

I have installed all the tokens as described.... any idea on what the issue is?

in settings for a user I entered API keys for:
1. Native Token Key
2. Native User Key

I did tried same api keys for native in settings, but it did not make a difference.
After exiting the ios app, clearing it from memory and relaunching it, I am allowed to enter user name and password, however, the busy circle come on momentarily but does not log me in..
