Re: Why do I sometimes/randomly get this "450 Transfer aborted. Link to file server lost" error?

@botg So the issue is really as described. If I remove the close call in socket_thread::close_socket_fd (and therefor leaking the fd) the upload succeeds. FileZilla is hard closing the socket without doing the full bidirectional shutdown. I can try to find out what's the best location to fix this bu...

Re: Why do I sometimes/randomly get this "450 Transfer aborted. Link to file server lost" error?

This can happen if for example not all data has been read from the socket but the socket gets forcefully closed. e.g. In TLS 1.3 (at least with openssl) per default two session tickets gets send during the handshake. During uploading data sockets usually don't need to be read from which upon finish ...

Re: Why do I sometimes/randomly get this "450 Transfer aborted. Link to file server lost" error?

Since filezilla also was linked against gnutls 3.6.5 and uploading didn't work I don't think it will start working with 3.6.6. Oh btw I forgot about another "client": Uploading with PHP also does work. That was actually one of my first tests. edit: and via curl it doesn't work. So I'm back to square...

Re: Why do I sometimes/randomly get this "450 Transfer aborted. Link to file server lost" error?

We have tested this now with different ftp clients and proftpd as server. All clients were compiled and run on the same system (updated fedora). * filezilla linked against gnutls 3.6.5 does not work * filezilla connected via tlswrap linked against openssl 1.1.1 does work * lftp linked against gnutls...
