AdiIRC

forgot to mention I can receive files in mirc over the same connection.

Did this start happening in 2016/07/12 ? if so try the 2016/07/12-1 update.

No. It has been happening since I started using adiirc a few months ago. Not sure of the exact build i started with anymore I am afraid.

Okay, first make sure no antivirus/firewall/antimalware is interfering with AdiIRC, e.g whitelist AdiIRC.exe.

Second go to the "Menubar" at the top of AdiIRC, click "File" -> "Rawlog", whith "Rawlog" window open, start a transfer, when the transfer fails, go to the "Rawlog" window, select the "Debug" tab and copy any relevant errors, then paste them here, you just have to select the text and it will be automatically copied to your clipboard.

No antivirus or firewall installed/functional. So definitely not that.

So it seems like its not erroring at all. Even though this is what the dcc window shows.

Also the file size on disk matches the DCC window.

I take it there is no relevant error messages in the "Debug" tab then ?

Correct. After a while the sender's client claims there is a time out and the connection failed. Again this connects and sends just fine in mirc. SO I know its not my network configuration.

Other tidbit. The bit of data received is also correct. So there is a proper connection being made.

I am out of ideas, would need to test the transfer myself to see what's actually happening

I am currently available on irc.efnet.org as user geekboy. Hop on and send me a PM. Or let me know where i can find you.
