    Hello,

    I have a new problem that has just appeared with my Android application.
    It can no longer access to my server. I have the following message

    D libc-netbsd: getaddrinfo: winstars.net get result from proxy gai_error = 0

    and the connection fails...
    The strangest thing is that it only appears on a tablet running Android 7.0
    With other devices, everything works fine! No changes in the code lately. I access the server with https requests.

    I renewed the Let's Encrypt certificate of my server but nothing works.

    I tried to put in my Manifest some stuff like android:usesCleartextTraffic="true" or to add a
    android:networkSecurityConfig="@xml/network_security_config" but nothing works...

    Until a few days ago, this tablet was accessing the data without any difficulties.

    Do you have a hint?

    Thank you!

    PS: I'm using Qt 5.15.2

      I think I have the answer to my question... https://community.letsencrypt.org/t/a-note-to-heavy-users-of-let-s-encrypt-change-affecting-android-users-starting-january-11-2021/134769

      But what can we do to get around the problem?

        Hi,

        Did you try to provide the full chain of certificates to your application ?
