(2) As to the Anonymous response (and the referenced, unfortunately also Anonymous, “other thread”), I do not see any sort of answer here. For instance, “all right, if I should be looking at one type of version-number instead of another type of number, what number should I be looking for, and how does this have any bearing as to why one module might be working and another is not?

Of course , this just means you sundialsvc4 don't understand basic debugging -- comparing version numbers of working modules and non-working ones, is like the first step to figuring out where a problem might exist, or how to side step it completely

I know that you can’t look at the server-logs of developer.apple.com (can you?), but I definitely would suggest looking in the system event-viewer (probably in Administrative Tools) to see if Windows logged anything of interest on your end. I’ll bet that it probably did, and, if it did, please add some of that information as a comment to your post.

This just means you sundialsvc4 have never used event-viewer

Hi sundialsvc4

(1) Bakkiaraj, if one module did allow the entire file to be downloaded successfully, “do you still have a problem?” Or, is your question now one of curiosity?

I can use Crypt::SSLeay but I want to use default IO::Socket::SSL, I do not want to use extra modules.
