    I'm working with Visual Studio 2019 version 16.1.6 . This seems to be the problem with Visual Studio 2019 . According to the link below: https://support.aspnetzero.com/QA/Questions/7132

    To fix the above problem, it was recommended to change modernhttpclient to modernhttpclient-updated . According to the link below: https://github.com/tmenier/Flurl/issues/453

    But I get the following error when calling the mobile app :

    When calling the following address, it executes correctly in the browser: http://192.168.1.103:8088/abpuserconfiguration/getall

    Do I have to change anything?

    Hi, the error might be caused by the default settings on android.

    Are you using Android 9 and above?

    Thank you for your follow up Yes,I tested with different api (26,23,22,16). I have the same problem for all of them.

    More explanation With each client request (such as a browser request) the request information is logged on the server side. But when calling xamarin, no data is logged on the server side. (With the documentation mentioned in previous posts)

    Hi,

    I've tried with the latest AspNet Zero (dev branch) without any issues.

    See this thread #5655

    After several days of trying, the problem was fixed by updating the Visual Studio version. Upgrade to version 16.2.3

    To inform the app development team: Upgrading the Visual Studio version works well without errors. Upgrading the ModernHttpClient version through the nugget from (modernhttpclient Version 2.4.2) to (modernhttpclient-updated Version 3.4.4) gives the following error: call failed : cleartext communication not enabled for client

    thanks :)

    Thanks for let us know. We will handle this while upgrading the nuget package.
