Thanks for your report. The libcurl.log clearly contains mysteries.

On line 579 it shows a "200 Port command successful" response from the server to the PORT command, and it then also logs a successful connect back from the server on the next line.

On line 582 it sends STOR to start the upload. And then the weirdo:

On line 583 it reads "200 Port command successful" as a response to that. It is wrong. It is actually wrong slightly before that as well.

Checking the corresponding network capture. Packet 12683 shows a "426 Connection closed; aborted transfer" which seems to come after the server has aborted the file transfer or something. That response code seems to not get read by libcurl (but I can't understand why) so it believes the transfer of image00009.jpg was fine. That's what breaks everything.

On the subsequent request, when libcurl connects and sends EPRT (line 572 in libcurl.log) it reads the 426 status which is completely out of sync, but libcurl then thinks of it as EPRT not working and tries PORT instead and then reads the EPRT response from that and that's a 200.

Can you repeat this problem?

Attaching both, a wireshark capture log plus log messages from libcurl when the problem occurs.
