    Hi Aki,<br>
    <br>
    I failed to disclose that the described problem occurs on iOS 13.0
    beta.<br>
    <br>
    After trying again and again, it appears that a bug in iOS 13.0 beta
    is the likely culprit. I am reading on Reddit that there is some bug
    in iOS with certificate trust...<br>
