AWS CLI - Uploading files with curl

Hi there,

I'm trying to upload some files to a Device Farm project. The documentation of AWS CLI is pretty clear (thank you very munch!) and it's really easy to schedule a run with a bunch of sentences. In my case I've created an upload (providing a correct arn project). All is fine at this point, but once I try to upload the file with curl, providing the signed url, there is a SSL error:

curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to prod-us-west-2-uploads.s3-us-west-2.amazonaws.com:443

This is a very common curl error and is widely spreaded on the internet forums. It was impossible to find a solution related with Amazon (or similar problem).

So I hope someone on this forums faced a similar issue.

There is my log of curl -vk "signed amazon url":

• TCP_NODELAY set
• Expire in 200 ms for 4 (transfer 0x162218bb120)
• Connected to prod-us-west-2-uploads.s3-us-west-2.amazonaws.com (52.218.128.5) port 443 (#0)
• ALPN, offering h2
• ALPN, offering http/1.1
• TLSv1.3 (OUT), TLS handshake, Client hello (1):
• TLSv1.3 (IN), TLS handshake, Server hello (2):
• TLSv1.2 (IN), TLS handshake, Certificate (11):
• TLSv1.2 (IN), TLS handshake, Server key exchange (12):
• TLSv1.2 (IN), TLS handshake, Server finished (14):
• TLSv1.2 (OUT), TLS handshake, Client key exchange (16):
• TLSv1.2 (OUT), TLS change cipher, Change cipher spec (1):
• TLSv1.2 (OUT), TLS handshake, Finished (20):
• OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to prod-us-west-2-uploads.s3-us-west-2.amazonaws.com:443

Finally my curl is using those libraries (just vanilla Curl Windows client):
OpenSSL 1.1.1a
brotli 1.0.7
libssh2 1.8.0
nghttp2 1.36.0
zlib 1.2.11

For any futher information just ask!
Thank you.
