Can't connect to self-signed WebDAV server

This discussion was created from comments split from: Unable to Sync.
  • Hi,

    I'm having problems connecting to my self-signed WebDAV server. I have the following setup at my server:

    -> I'm using my own WebDav server: the MacOX High Sierra (10.13.6) WebDAV version of 2017
    -> I have my own self-signed certificate: signature algorithm SHA-256 with RSA Encryption; version 3; RSA key size 2.048

    -> I'm using port forward to bypass my provider restrictions. For example, I mapped an external port x.x.x.x:50443 to internal port

    I can connect to my WebDAV server through MacOS "Connect to Server" tool (with CMD + K) without problems.

    In Zotero App in a macOS Catalina (10.15.7) I'm keep getting the following error:

    ===== uses an invalid security certificate.

    The certificate is not trusted because it is self-signed.
    The certificate is only valid for


    I followed the instructions in but I got no success in connecting using Zotero app (version 6.0.12) with my WebDAV server.

    I did the following setup in Zotero's "Sync" Preference option:


    Can anyone help figure out what the problem is? I'd really appreciate any help.

    Thanks in advance!

    I'm afraid there's no more information we can provide than what's on that page. The steps are correct — I've just tested with the latest Firefox version.

    To be clear, for a self-signed cert, it's just the cert_override.txt file, but note the detail about the format change in newer Firefox versions.
