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: Response{protocol=h2, code=401, message=, url=}

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

I made all the instruction here (7.2)

and the configuration here

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