SSL Certificate from let's Encrypt not trusted

  • Hi,

    I switched from a self-signed certificate accepted by CAdroid, to a new Let’s Encrypt certificate, with OwnCloud (I also removed CAdroid)
    My server is well configured (my ownCloud instance has been rated A on, but when I try to connect to my caldav or carddav URL, I have this error : “Untrusted certificate in certificate path. See FAQ for more info”
    But I didn’t find anything on the FAQ about my problem.

    Versions :

    • Android 4.4.4
    • ownCloud 8.2.2
    • DAVdroid 0.8.4

    Any idea ?

    What’s your domain / host name?

  • Oh sorry, I only have a B on this server.
    Probably the issue is coming form the chain issue.
    My host is :
    The SSL test is :

    My nginx SSL conf is :

            ssl on
            ssl_certificate /etc/letsencrypt/live/;
            ssl_certificate_key /etc/letsencrypt/live/;
            ssl_trusted_certificate /etc/letsencrypt/live/;
            ssl_client_certificate /etc/letsencrypt/archive/;

    I’m looking forward and I come back.

  • OK now my problem is different. I will open another topic.
