When attempting to crawl a website, the crawl immediately cancels without copying any files. The Errors tab displays an error stating
An existing connection was forcibly closed by the remote host
An unexpected error occurred on a send
Websites that are secured via SSL used cryptographic protocols to communicate securely between the client and the host. If the client doesn't support the protocol required by the server, communication attempts will fail.
WebCopy version 1.2 and lower
Versions of WebCopy prior to version 1.3 only support the SSL 3 and TLS 1.0 protocols and will not be able to copy websites that only support TLS 1.1 or higher. To copy these websites, WebCopy would need to be upgraded.
WebCopy version 1.3 onward
Version 1.3 and above supports SSL 3.0, TLS 1.0, 1.1 and 1.2. All protocols are enabled by default.
