"Empty reply from server" when uploading application to Sauce Storage using curl

You may experience an issue when uploading an application to our Sauce Storage that gives an error:

curl: (52) Empty reply from server

This has to do with  the deprecation of TLS 1.0 and 1.1 on our service, is seen on older versions of curl that are using HTTP/2 but cannot receive the response due to TLS 1.0 and 1.1 being deprecated.

Please use either of the following ways to resolve this:

• Upgrade curl to a newer version (we've seen best results with 7.71.1)
• Add the --http1.1 flag to your curl command
• Use a REST library or REST client (e.g. Postman) to upload the app
