PuTTY is not an SFTP client. If no SFTP client work, it's a server-side problem.

                Can you connect and retrieve the directory contents using any other SFTP client?
                
            
        
    
    
        
        
            
            
                Hello Community,
I need to connect via WinSCP from my Windows Computer at home to a Computer at a University. I am using the Uni VPN to connect to the local network. WinSCP worked fine until suddenly it started to always timeout while reading the remote directory. The authentification works so i think that up to that point the connection works fine. Help would be really appreciated.
I used to use a SFTP connection.
Best Regards
