Going by the cURL docs, --retry only retries transient errors: https://curl.se/docs/manpage.html#--retry

I'm not sure if "Empty reply from server" is a transient error, at least it's not in the list. It looks like there's --retry-connrefused to add one more error type to the retry, but that also doesn't read like "Empty reply from server". Let's try merging this to see if it helps, but I wouldn't be surprised if it doesn't :D
