CURLE_PARTIAL_FILE error if downloading file in blocks (CURLOPT_RANGE) larger than file size

[kupavcevdenis]

I did this

When trying to download file (FTP) in blocks (CURLOPT_RANGE, 0-262144) larger than file size I get CURLE_PARTIAL_FILE error

Set options.

CURLOPT_HTTPGET, 1
CURLOPT_NOBODY, 0
CURLOPT_HEADER, 0
CURLOPT_UPLOAD, 0
CURLOPT_FAILONERROR, 1
CURLOPT_FOLLOWLOCATION, 1
CURLOPT_RANGE, 0-262144

Probably the cause of the error
transfer: conn close on paused upload · curl/curl@30de937
