I use UBot 4.2.20 (UBot 5 is not reliable yet), I try to upload file through FTP on my server. I connected to FTP successfully, and I can create folders and delete them through FTP connection. When I try upload file I can see FTP server logs shows that it is in passive mode. The Ubot script returns error that FTP server failed to respond correctly on specified server with port different then 21 (port was set to 21 in FTP connection command). I wondering if there is way to force active mode for file upload? If you had the same issue in past and know how to fix it, please help.
