PATHwhen I tried connect to a site using a proxy. Could WinSCP check that the program being used as the "Local proxy command" exists and warn the user if it does not (either in the GUI or in the logs)?
Currently I just get a log like this if I use a proxy command that doesn't exist:
. 2022-07-25 19:25:49.569 Starting local proxy command: foo.exe firstname.lastname@example.org -agent -nc 10.204.221.51:22 . 2022-07-25 19:25:49.582 We claim version: SSH-2.0-WinSCP_release_5.21 . 2022-07-25 19:25:49.582 Connected to 10.204.221.51 . 2022-07-25 19:25:49.582 Waiting for the server to continue with the initialization . 2022-07-25 19:25:49.582 Looking for incoming data . 2022-07-25 19:25:49.582 Looking for network events . 2022-07-25 19:25:49.583 Remote side unexpectedly closed network connection . 2022-07-25 19:25:49.583 Using non-standard protocol or port, tunnel or proxy, will not knock FTP port. * 2022-07-25 19:25:49.625 (EFatal) Server unexpectedly closed network connection.
