"Could not connect to WebDAV server"


The error message indicates that connection to the WebDAV server is not established. Any further operations with remote server will fail until reconnection attempt is made.


The error may be caused by connectivity issues such as firewall or antimalware whitelisting. Make sure that local machine can connect to the remote server—no firewall is blocking outgoing connections on the client, and incoming connection at the server.

Double check that your provided username & password, thumbprint, certificate and passphrase is valid and are in supported format. To pinpoint the problem, enable connection debugging option.

If the error is due to an unsupported TLS version, ensure that you are not restricting the latest TLS version in the connection's custom options. Also, verify that your server software is updated to support the latest TLS standards.
