--- Comment #8 from Volker Krause <vkra...@kde.org> --- Hm, that sounds like the device CA certificate chain is incomplete, and for Android <= 7 and Let's Encrypt certificates that isn't even entirely implausible. Can you check if your device has the "Internet Security Research Group (ISRG) X1" certificate installed? Here this is under Settings > Security & privacy > Encryption & credentials > Trusted credentials, but this can of course vary from one Android version to the next. -- You are receiving this mail because: You are watching all bug changes.
