With WinSCP 5.8.1 beta i cant connect to any SSH site.
Only when using a Socks or http proxy.

The following error occurs imediatly after connecting:

"Server sent command exit status 2147483647"

I'm not sure I understand. Do you have the problem when connecting over proxy or when connecting directly?

Can you connect correctly with any other SSH client or older version of WinSCP?

Hi,

yes regular connection works fine.
Only when using a socks5 proxy, the error occurs

Yes with an older version of winscp it works also fine.
Just when i replace to the new beta binary this happens.
Also tried with a fresh empty config file, same problem always only when using a socks proxy

Please attach a full log file from both versions for a comparison.

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

i always use the latest beta version when it comes out and have always proxy in my config

Thanks. I can reproduce this now too.

Can you send me an email, so I can send you back a development version of WinSCP for testing once I fix this? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.
