Troubleshooting Outbound WebDAV

Outbound WebDAV connections can fail for several reasons. Some errors are fixed by changing settings in your Files.com site. Others must be addressed on the remote WebDAV server or its firewall.

Files.com displays connection errors when you create or edit the Remote Server, and records errors for individual file and folder operations in the Outbound Connections log. Some errors begin with a bracketed prefix that identifies the Remote Server by ID and internal name.

Hostname Issues

The error Hostname is invalid means Files.com cannot resolve the hostname of the remote WebDAV server.

WebDAV addresses are often shared as full URLs that start with https:// and end in a folder path. Enter only the hostname, without a protocol or path, and use a hostname that is resolvable from the public internet.

Firewalls and Connectivity

The error Host is unreachable means Files.com received no response from the remote WebDAV server at the configured hostname and port.

Confirm the port with the administrator of the remote server.

Firewalls on the remote side commonly restrict which IP addresses can connect. Ask the operator of the remote site's firewall to allow connections from Files.com IP addresses, and review the IP addresses your site uses for outbound connections to confirm that none of them are blocked.

Authentication Failures

The error Authorization failed means the remote WebDAV server rejected the username and password configured for the connection.

Confirm the credentials with the administrator of the remote WebDAV server, and update the Remote Server if the credentials have changed.

SSL Certificate Issues

The error SSL connection error means Files.com could not establish a secure connection to the remote WebDAV server. This occurs when the certificate presented by the remote server is self-signed, expired, not signed by a trusted certificate authority, or does not match the hostname used for the connection.

Ask the administrator of the remote WebDAV server to install a current certificate that is signed by a trusted certificate authority and matches the hostname. To check the remote server's certificate, use an online tool such as the SSL Shopper SSL checkerExternal LinkThis link leads to an external website and will open in a new tab or the DigiCert SSL certificate checkerExternal LinkThis link leads to an external website and will open in a new tab.

Permission Issues

The error Not authorized to perform this operation means the remote WebDAV server denied the operation for the account that Files.com uses to connect.

The Outbound Connections log shows which operation failed. Ask the administrator of the remote WebDAV server to grant that account the permission the operation requires.
