FtpException thrown downloading file with 49.0.2 works in 49.0.1 about fluentftp

[FanDjango]

V50.0.0 has been released. Any work on your issue should be re-analyzed against this new release instead of V49.0.2 (see previous post).

Thanks for this report and it's completeness.

FluentFTP 49.0.1 -> 49.0.2: there were some changes to the handling of "Progress reporting" - these, after release of 49.0.2 were fixed and are due for release soon. So, if your code is using "Progress", you might want to test (just as a temporary measure) not using a progress callback in your code.

If it does not resolve the problem: We need to analyze your problem in more depth.

If it does resolve the problem: I would be very interested in you accessing the current master on GitHub and testing that.

Once again, if that resolves the problem, then this information would be valuable to confirm all is well.

Otherwise, we are back to square one, and need to do more analysis.

Note: Handling of stale data and what to do / how to report failed transfers is also improved in current master, which will help debugging.

What I do not understand, but you may be able to shed light on: You report the exception, but in the log I cannot see exactly at what point of the sequence the exception occurred. I surmise it occurred right after

Am I correct?

If you look at the recent issues:

#1518 and #1519 more or less covers this - in your log, I can see that the SIZE command is not allowed and thus the problem is quite clear.

So I really think that the current master fixes your problem, it is just not released yet.

Workaround: Don't use progress or allow the SIZE command on the server.

V50.0.0 resolves the issue I reported (as did not using progress in v49.0.2.)

Thanks!
