The SSL handshake failed as the server certificate validation has failed.
The server certificate is either:
Uses incorrect/missing chain
Has an incorrect CN.
As an immediate workaround, you can use HTTP in the upload command. This implies that you need an HTTP server to host the file.
To fix the server certificate error do a packet capture on the server and find out which of the above causes the SSL handshake to fail.
