Hello,
I'm running a script on Windows Server 2008R2 that calls WinSCP to download some files from a FTPS server that I do not control. If the remote server has been misconfigured (has happened a couple of times during this project) the script will hang on waiting for WINSCP because it keeps trying to reconnect to the server. WINSCP appears to try to reconnect indefinitely. This morning WINSCP tried for 45 minutes before the server was able to be fixed.

So my question is can I tell WINSCP to abort after the first time the passive connection fails so the script can move along? The log appears to show that WINSCP should be asking me if I want to retry and the batch option is set to abort so I thought I was good to go. Script and Log portion are below. WINSCP version 5.9.3 build 7136.

Thanks in advance.
