Connect failed. Error=0x80043112

Hi,
 
I am receiving a 'Connect failed. Error=0x80043112' message when attempting to connect to an FTP host (21) using SmartFTP 4.1.1289.0 (Ultimate).
 
I have been able to successfully connect to other hosts from my machine so I don't think that it is a firewall issue on my side.
 
I am also able to connect to this specific host from another machine using SmartFTP 4.1.1289.0 (Pro).
 
Any suggestions?
 
Thank you.

I got the same error now in 5.0.1353.0. Connecting to the server has always worked fine (and still works fine over putty), but fails with SmartFTP.

Strange thing is that it does something with certificates here even though I only activated "passworc" as authentication mechanism and using keys would not work because I have none.

Contact support: menu: Help->Request support and send the server ip.

I too am receiving this error.    Yet only since an update.   previous versions were running correctly.
   
"An established connection was aborted by the software in your host machine
Connect Failed.   Error=0x80043112
 
Running Win 7 64bit.

SmartFTP  5.0.1354.0
 
As requested by support I have uninstalled Firewall and Anti Virus.
Error still exists.
 
I cannot even connect to ftp.smartftp.com
 
I also cannot do a fresh install of Win 7 as I have no other computer available.
 
Any help gratefully received.
