we have a strange effect with an external WebDAV server. The authentication is two-step (server asks for re-connect incl. certificate) and the transfer of small files works without problems. For large files the transfer is reset (just before the end) and starts again. Then at 100% the transfer ends with an SSL error and the file disappear.
It seems that not the size of the transfer is crucial but the actual time. If we throttle the small file (so that the transfer takes longer) then the small file also fails with the same error message.
The logfile is attached!
Error is shown in line 1413 @ 2021-01-19 14:55:46.718
I also added a screen capture (mp4) of the transfer. You can see that the whole transfer resets at ~80% and starts again before the final error message is shown. The video only shows the transfer of the 2nd (large) file, the logfile includes the whole session (login with small and large file transfer).
Thanks for any help!
