It seems as of the update to 3.0, the ftp-tls component sends duplicate instances of commands (I checked against the last 2.8 version and it wouldn't)

EG:
<snip, parts above here are duplicate as well>
250 CWD command successful

At this point the download runs for a bit, then stalls claiming 'transfer incomplete' resume restarts it but it gets at most about 10mb (rough estimation) before claiming incomplete again, resume does not appear to work. (the same FTP server configuration worked fine in version 2.8x, excluding the APPE errors)

I could not yet replicate the issues. What are the exact steps to reproduce?

Duplicate for #2057. Please uncheck 'Send 'no operation' command to keep connection alive in Cyberduck → Preferences → Connection until this is fixed.
