Description

Hi

It appears as an error occurs if the remote SFTP server tries to renegotiate the SSH connection. I'm currently getting the error:
"Message type 94 is not valid in the current context."

The server I'm connecting to is a Rebex BURU SFTP. On their forums they discuss the issue:
https://forum.rebex.net/12973/sftp-file-downloads-hang-for-large-files

Research direction

Start by reproducing the failure against a Rebex BURU SFTP server, particularly during a large file download as described in the linked forum discussion. Trace the SSH message handling around “Message type 94 is not valid in the current context.” Done means the connection continues successfully when the remote server renegotiates the SSH connection.
