 If the server isn't using a self-signed certificate (i.e., it's chained to a root certificate that's trusted in browser stores), this error generally occurs because the proxy or WebDAV server isn't serving the necessary "intermediate certificate" for secure connections, and Zotero (like Firefox, on which it is based) won't download it on its own. Without an intermediate certificate, it's impossible to determine whether the connection (which might include login details) is secure, and the connection fails. If the server isn't using a self-signed certificate (i.e., it's chained to a root certificate that's trusted in browser stores), this error generally occurs because the proxy or WebDAV server isn't serving the necessary "intermediate certificate" for secure connections, and Zotero (like Firefox, on which it is based) won't download it on its own.
