Open edX android app - can't login

I try to build the android app for our openedx instance. the app was built and launched but when I tried to log in android studio emulator I got an error:

org.edx.mobile.http.HttpStatusException: Response{protocol=h2, code=401, message=, url=https://madrasafree.com/api/mobile/v0.5/my_user_info}

How can I check what the problem is and solve it?

I made all the instruction here (7.2)

https://edx.readthedocs.io/projects/edx-installing-configuring-and-running/en/latest/mobile.html#configuring-mobile-application-features

and the configuration here

Solved
It was fixed after I added WSGIPassAuthorization On to httpd-lms.conf as written here
