Unfortunately I have the following problem when creating a connection to an external SFTP server.
- Remote side unexpectedly closed network connection -
From the attached log data I gather that the connection is separated from the proxy server after 30 seconds, am I interpreting the log correctly?
If I contact the SFTP server via Filezille with the same settings (SFTP + Proxy), a connection is established, see log.
I can reproduce the behavior with a second external SFTP server, so I assume that the problem is not with the SFTP server but with the proxy or the firewall.
Does anyone have a tip for me where I can look there?
