On immediate rerun, a full file is uploaded (if we wait few minutes, 0-length file will get uploaded). Below are the traces from initial and subsequent calls. We also tried using same version curl on a linux box, without any issues. We also downloaded latest version of curl from curl for Windows, "curl 7.65.3 (i386-pc-win32) libcurl/7.65.3 OpenSSL/1.1.1c (Schannel) zlib/1.2.11 brotli/1.0.7 WinIDN libssh2/1.9.0 nghttp2/1.39.2", and its also working correctly. >> Unfortunately, the server we're uploading to belongs to a client, and we can't see if this is an issue on a server side.

FYI Cygwin curl current version produces: $ curl --version curl 7.65.3 (x86_64-pc-cygwin) libcurl/7.65.3 OpenSSL/1.1.1c zlib/1.2.11 brotli/1.0.7 libidn2/2.2.0 libpsl/0.21.0 (+libidn2/2.0.4) libssh/0.8.7/openssl/zlib nghttp2/1.37.0 Release-Date: 2019-07-19 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smb smbs smtp smtps telnet tftp Features: AsynchDNS brotli Debug GSS-API HTTP2 HTTPS-proxy IDN IPv6 Kerberos Largefile libz Metalink NTLM NTLM_WB PSL SPNEGO SSL TLS-SRP TrackMemory UnixSockets -- Take care.
