lftp Upload hang at 100%

I have a script that upload my files with FTPS. It work well with small files, but on 70mb the transfer end with a message "100% - Waiting for transfer to complete". The file is entirely uploaded but connection stay open and go in timeout forever, and the script don't execute the following command.

I tryed to read manual but I don't have idea which options should I use to solve. Thanks for your help.

I'm using Debian Jessie package of lftp v. 4.6.0-1+deb8u1.

I'm frequently running into a similar, if not the same error. The transfer of a particular file succeeds (100% transfer status and the file is verifyably complete), but the server closes the connection to lftp and lftp hangs itself up in a reconnect loop.

I stopped having the reconnect loop, but I still get connection terminations (but that is now client independent). For that, luckily, I managed to use the --loop flag with success.

With lftp 4.8.4 i got gnutls_record_recv: Die TLS-Verbindung wurde nicht ordentlich beendet. Assuming EOF.

I came here because of this problem, too. I don't use SSL/TLS.

=> Oh, sorry. It works, but it takes a long time.

when i experienced this, it turned out to be a false negative because of how i was using the command. in my case, i told it a file existed (when it didn't) for a parallelized mput command.

i setup a script to transfer a, b, and c from my local computer to example. turns out b wasn't there. lftp notifies me on launch that it couldn't find b, but then continued to upload a and c. once it was done, it stated waiting for transfer to complete at 100% for awhile and then sent a non-zero error code. i checked example and sure enough, a and c were complete.

my solution was to find the circumstances when b wasn't present and modified the script. no error now.

+1 lftp version 4.9.2

Does not work:

lftp -c " \
    set ftp:ssl-allow true; \
    set ftp:ssl-force true; \
    set ftp:ssl-protect-data true; \
    open -u <username> -e \" \
        mirror -X .* -X .*/ --reverse --verbose --delete source_dir/ target_dir/; \
        bye\" \
    remote_host \
"

Does work:

lftp -c " \
    set ftp:ssl-allow false; \
    open -u <username> -e \" \
        mirror -X .* -X .*/ --reverse --verbose --delete source_dir/ target_dir/; \
        bye\" \
    remote_host \
"

Although this gives me a workaround, I do not consider it a solution in any sense -.-
