I am running into a very strange problem:
I can connect on my FTP server (so no login issues), I can download files from my server, but I can't upload anything. The connection dies within a couple seconds.I have the required permissions to upload.
I have tried with other computers and it works fine (using the exact same settings), so there is definitely something on my computer preventing me from uploading.
There is no firewall and no router.
Uploads fail without specific error message: The thread stops, and the client logs back in, open the folder, tries to upload, fails, and starts again.
I am using Filezilla, but I have tried a handful of other programs as well, with the same (lack of) results. Besides, I can connect from other computers using Filezilla.
Any idea what could be the source of the problem?
