Thanks! Ok and what about 5.19.6?
I tried with both. Unfortunately not working. I posted the logs. Thanks for your help!
I use WinSCP for several years but this time I am not able to get it working. The needed server changed from FTP to SFTP with key. I got it working locally! But in the cloud there must be a mistake. FileZilla got it but I want to keep using WinSCP. Maybe any ideas? I tried with proxy and using SSH tunnel. I think the logs would show better what I did :-)
