[SOLVED] Timeout after every WebDAV transfer, yet successful transfers

When trying to upload files with the WebDAV protocol (on this specific server), I am getting the following error:

Copying files to remote side failed.

Network error: Connection to "[IP Address]" timed out.
Could not read status line: connection timed out

What's strange is that despite getting this error every time, the transfers appear successful (unless I try transferring multiple at once, at which point the error will prevent the queued items from transferring).

Hopefully the log will help you find out what's going wrong.

(problem solved, log removed)

Try to turn off Preserve timestamp transfer option:

That fixed the problem. Thank you very much :)
