We have a FTP upload that only works when we don't check the Write FTP conversation to History.

We are using
ftps (implicit) 990
passive mode - strict

We get the following error message when we are using the option;

16-06-02 09:29:20.001;I;FTP Library 3.5.3.731;;

We are using 4.9.4 (beta)

Is this a known issue?

Hi,

Yes, this is a known issue with the beta version, we are working on a fix for it.
