You can connect to any WebDAV compliant server using both HTTP and HTTP/SSL. Mutual TLS with a client certificate for authentication is supported.
Settings are specific to service providers. Use the provided connection profiles.
All connection profiles are available through the Preferences → Profiles tab.
Basic Authentication should only be used when using a secured connection over TLS (HTTPS).
Both HTTP Basic Authentication and Digest Authentication are supported.
Used when connecting to SharePoint using WebDAV.
Download and use the WebDAV (Integrated Windows Authentication) profile to connect to the server using Integrated Windows Authentication.
Choose WebDAV (HTTP/SSL) as the connection protocol to secure the connection using SSL. Interoperable with TLSv1.3 and TLSv1.2.
TLSv1 and TLSv1.1 deprecation
TLSv1 and TLSv1.1 are no longer supported as of
Mutual (two-way) TLS with a client certificate for authentication is supported.
Prompt to Authenticate with Certificate When Negotiating Secure (TLS) Connection
When a server requests a client certificate for authentication, a prompt is displayed to choose a certificate with a private key that matches the given issuer name requested from the server. Matching certificates are searched for in the Keychain on macOS or the Windows Certificate Manager respectively.
Select Client Certificate in Bookmark
You can also pre-select a certificate to use for authentication when editing the bookmark.
If the certificate is not trusted by the system, you are asked to make an exception if you still want to connect to the site that cannot be verified. This failure during certificate trust verification is most often the case when the certificate is invalid either
Because the hostname does not match the common name in the certificate. You will get the error message You might be connecting to a server that is pretending to be….
The certificate is self-signed or signed by a root authority not trusted in the system.
The certificate is expired.
You can temporarily or permanently allow connecting nevertheless by choosing Continue. To remember your choice, select Always Trust….
You can edit custom properties using File → Info → Metadata.
You can enable custom origin Amazon CloudFront (Content Delivery Network) distribution using File → Info → Distribution (CDN).
You can access publicly readable Subversion (SVN) repositories running behind
mod_dav_svn of Apache httpd using anonymous WebDAV (HTTP) access with Cyberduck. For example the Cyberduck Source Code Repository.
Saving the modification dates requires support from server storing metadata in custom namespace.
If your server requires the use of UTF-8 character set for authentication, set the hidden configuration option
This only applies if you access a Synology Diskstation.
If the file listing shows additional folders of the file tree that are usually not visible try to uncheck the checkbox disable directory browsing within the advanced settings for a shared folder on your Synology Diskstation.
The virtual host set up by the hosting provider is most possibly misconfigured. It must accept TLS connections with SNI (Server Name Indication) extension (RFC 4366). The hostname must match the common name in the server certificate. In Apache httpd configurations, add a
ServerAlias configuration directive with the hostname you use to connect.
You can verify the wrong server setup by running
openssl with server name indication (SNI) enabled.
openssl s_client -servername <servername> -tlsextdebug -msg -connect <servername>:443
This will print
<<< TLS 1.0 Alert [length 0002], warning unrecognized_name
during the handshake, if there is a configuration problem.

Expect: 100-continue to make sure a server accepts an upload before data is sent. You can disable the use of this feature when there is an interoperability issue by setting the hidden option
Some servers (cPanel) have invalid return GZIP encoded content. This error may not be seen with other clients that do not enable content compression. An invalid HTTP response status line is sent and the content size does not match the content length set. As a workaround, you can disable support for content compression. Set the hidden option
Require directive in Apache HTTPD tests whether an authenticated user is authorized according to a particular authorization provider and the specified restrictions. You should configure it to return a 403 HTTP status code when authorization fails using the
AuthzSendForbiddenOnFailure directive. Refer to mod_authz_core.
If authentication succeeds but authorization fails, Apache HTTPD will respond with an HTTP response code of ‘401 UNAUTHORIZED’ by default. This usually causes browsers to display the password dialogue to the user again, which is not wanted in all situations. AuthzSendForbiddenOnFailure allows changing the response code to ‘403 FORBIDDEN’.
If you are running an Apache configuration make sure to disable
php-fpm. Refer to our best practice for Nextcloud and ownCloud installations.
Deployments with WebDAV on Apache HTTP server with the mod_evasive module may block requests leading to permission failures with
403 HTTP errors returned by the server.
