I did quite a bit of testing and trying to figure out what's causing
this....I've found one consistent behavior
If I put this host in the base
URLhttps://superb-sea2.dl.sourceforge.net/project/wsjt/
I get a consistent 5 "connection closed" messages every time. I do not have
http only checked.
I do get the first 6 files successfully downloaded from that host and it's the
last 5 that fail.
I then added the time delay in this patch (bumped up to 2 seconds and added a
sleep to prevent CPU usage as you noted). The sleep does allow the reply to
get deleted...related perhaps?It now works every time....albeit
slower.https://www.dropbox.com/s/yh86jlrp4ue91io/remotefile.patch?dl=1
I'm compiler with QT5.5 on Windows 7 64-bit.
However, since the connection is encrypted it is a bit difficult to see what's
going on.
The packet count from a windump capture shows 11 small transactions and 6
larger ones as you would expect -- it doesn't include the directory
download...capture was started after the window was opened. But I don't see a
difference for a set of 5.

There aren't any refused connections in the 11 sessions from 57674-57684.The
only suspicious thing is there are 5 sessions with 143:418 and 6 with 143:420
which may signify some different response from the server perhaps?

Below are the small 11 sessions which other than as noted above all look sane...

I was getting several "Network Error - connection closed" messages when
testing the sample downloader with https very consistently.
This patch slows down the process of downloading the remote samples a bit
which so far I haven't been able to break again.
I have a fast internet connection -- perhaps those with slower connections
may need more of a delay.
Hi Mike, thanks for the patch. I would like to understand the root problem
here before making any changes. The proposed patch has an issue in that it may
consume considerable CPU resource if there are no outstanding events to
process. A timer would be safer. But as I said I would like to understand the
root issue first. 73
