Hi

I am getting this problem when I am transferring files. It is OK for for smaller files (< 1.5 MB) but anything larger than that will exhibit the problem. It is happening to 2 different transfers, which run on different hosts and with different destinations servers (both provided by third parties) I suspect our proxy server is causing the problem but our network team have not yet identified a problem, are there any settings that can make the transfer more resilient and allow the transfer to continue?

I have tried with the latest version and get the same problem.

WinSCP should at least try to reconnect and resume the transfer. Does it?
